The clk_init_data structure contains several mutually-exclusive members
for different methods to specify the possible parents of a clock,
prompting drivers to initialize only the members they need. However,
not initializing all members may cause subtle issues, which are only
exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is
enabled.
Make sure all members are fully initialized, to avoid such bugs, and to
prevent future breakage when converting drivers to a different method
for specifying the parents.

It has been concluded by comparing the gate clock masks and vendor code
between PXA1908/28 that PXA1908's APBCP, similarly to PXA1928's APBC,
has controllable reset lines. Describe these in the driver for
correctness.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all clk drivers to use .remove(), with the eventual goal to drop
struct platform_driver::remove_new(). As .remove() and .remove_new() have
the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The PXA168 has a peculiar setup with the AXI clock enable control for
the SDHC controllers. The bits in the SDH0 register control the AXI
clock enable for both SDH0 and SDH1. Likewise, the bits in the SDH2
register control both SDH2 and SDH3. This is modeled with two new
parentless clocks that control the shared bits.
Previously, SDH0 had to be enabled in order for SDH1 to be used, and
when SDH1 was enabled, unused bits in the SDH1 register were being
controlled. This fixes those issues. A future commit will add support
for these new shared clocks to be enabled by the PXA168 SDHC driver.

Now that clk_register_mux_table takes a const u32 *, we can declare the
mux tables as const u32[].

pm_clk_suspend()/pm_clk_resume() are defined as NULL pointers rather than
empty inline stubs without CONFIG_PM:
drivers/clk/mmp/clk-audio.c:402:16: error: called object type 'void *' is not a function or function pointer
pm_clk_suspend(dev);
drivers/clk/mmp/clk-audio.c:411:15: error: called object type 'void *' is not a function or function pointer
pm_clk_resume(dev);
I tried redefining the helper functions, but that caused additional
problems. This is the simple solution of replacing the __maybe_unused
trick with an #ifdef.

'clk-const' and 'clk-mmp2' into clk-next
* clk-semicolon:
clk: meson: use semicolons rather than commas to separate statements
clk: mvebu: ap80x-cpu: use semicolons rather than commas to separate statements
clk: uniphier: use semicolons rather than commas to separate statements
* clk-axi-clkgen:
clk: axi-clkgen: Set power bits for fractional mode
clk: axi-clkgen: Add support for fractional dividers
* clk-qoriq:
clk: qoriq: modify MAX_PLL_DIV to 32
* clk-baikal:
clk: baikal-t1: Mark Ethernet PLL as critical
* clk-const:
clk: pxa: Constify static struct clk_ops
* clk-mmp2:
clk: mmp2: Fix the display clock divider base

The LCD clock dividers are apparently based on one. No datasheet,
determined empirically, but seems to be confirmed by line 19 of lcd.fth in
OLPC laptop's Open Firmware [1]:
h# 00000700 value pmua-disp-clk-sel \ PLL1 / 7 -> 113.86 MHz

The kernel test robot points out two harmless warnings in the
mmp clk drivers:
drivers/clk/mmp/clk-pxa168.c:68:13: warning: no previous prototype for 'pxa168_clk_init' [-Wmissing-prototypes]
drivers/clk/mmp/clk-pxa910.c:66:13: warning: no previous prototype for 'pxa910_clk_init' [-Wmissing-prototypes]
Fix these by including corresponding header file.
