pmdomain: imx: Make IMX8M/IMX9 BLK_CTRL tristate
Convert IMX8M_BLK_CTRL and IMX9_BLK_CTRL from bool to tristate
to allow building as loadable modules.
This change is required to support Android devices using Generic Kernel
Image (GKI) kernels, where SoC-specific drivers must be built as loadable
modules rather than built into the core kernel image.
For i.MX8M and i.MX9 devices running Android with GKI kernels, the
BLK_CTRL drivers therefore need to be loadable. Without tristate
support, power domains cannot be initialized correctly, making these
systems non-functional under GKI.
Add prompt strings to make these options visible and configurable
in menuconfig, keeping them enabled by default on appropriate platforms.
Also remove the IMX_GPCV2_PM_DOMAINS dependency from IMX9_BLK_CTRL.
This dependency was incorrect from the beginning because i.MX93 uses a
different power domain architecture compared to i.MX8M series:
- i.MX8M uses GPCv2 (General Power Controller v2) for power domain
management, hence IMX8M_BLK_CTRL correctly depends on it.
- i.MX93 uses BLK_CTRL directly without GPCv2. The hardware doesn't
have GPCv2 at all.
