mtd: nand-omap2: Move omap_nand_ids[] to raw nand driver
Defining a static array in a header results in each .c file that
includes the header (here: drivers/memory/omap-gpmc.c and
drivers/mtd/nand/raw/omap2.c) to contain a copy of that array when
compiled to an object file.
With sizeof(struct of_device_id[3]) ≥ 588 having omap_nand_ids[] twice
just to do two string comparisons is quite some bloat. So move
omap_nand_ids[] to the nand driver which actually needs that array for
its module meta data and do the compatible check by hand.
bloat-o-meter reports for drivers/memory/omap-gpmc.o (ARCH=arm):
add/remove: 1/2 grow/shrink: 1/0 up/down: 28/-588 (-560)
Function old new delta
gpmc_probe_generic_child 2108 2136 +28
omap_nand_ids 588 - -588
Total: Before=18114, After=17554, chg -3.09%
(drivers/mtd/nand/raw/omap2.o doesn't change).
This allows to drop <linux/mod_devicetable.h> from
include/linux/platform_data/mtd-nand-omap2.h (which is my original
motivation for this change). Note that this header isn't needed in the
two drivers because omap-gpmc.c doesn't use any device id struct and for
the nand driver omap2.c of_device_id is already provided via
<linux/platform_device.h>.
