The DT based MSM platforms can join the multi-platform builds, so
introduce a DT based ARCH_MSM option. This option allows DT based
MSM platforms to be built into the multi-platform kernel. Also
introduce a hidden ARCH_MSM config that both the DT and non-DT
platform support code select to avoid churn in places that depend
on CONFIG_ARCH_MSM.

ERR007265: CCM: When improper low-power sequence is used, the SoC
enters low power mode before the ARM core executes WFI.

Software workaround:
1) Software should trigger IRQ #32 (IOMUX) to be always pending
   by setting IOMUX_GPR1_GINT.
2) Software should then unmask IRQ #32 in GPC before setting CCM
   Low-Power mode.
3) Software should mask IRQ #32 right after CCM Low-Power mode is
