That select doesn't work for me and gives:
warning: (ARM_SCPI_POWER_DOMAIN) selects PM_GENERIC_DOMAINS_OF which has unmet
direct dependencies (PM_GENERIC_DOMAINS && OF)
Followed by link errors due to missing symbols.
I think you need to select PM_GENERIC_DOMAINS as well. Or perhaps just
instead of, as PM_GENERIC_DOMAINS_OF defaults 'y' and isn't user
selectable. From kernel/power/Kconfig ...
config PM_GENERIC_DOMAINS_OF
def_bool y
depends on PM_GENERIC_DOMAINS && OF
