[PATCH 1/2] arm64: select APPLE_PMGR_PWRSTATE for ARCH_APPLE

[Janne Grunau]

Critical devices like the NVMe on Apple silicon systems depend on
APPLE_PMGR_PWRSTATE and others are powered down coming out of reset so
select APPLE_PMGR_PWRSTATE to ensure these devices work. Since the
systems are not totally unsusable (boot to initramfs is expected to
work) allow !PM builds without APPLE_PMGR_PWRSTATE.
