Since pm.h provides a helper for system no-IRQ PM callbacks,
switch the driver to use it instead of open coded variant.

I think you could do:

.pm = IF_PTR(IS_ENABLED(CONFIG_ARM_PSCI_FW), pm_sleep_ptr(&sh_pfc_pm)),

Then you wouldn't need the #if defined(CONFIG_ARM_PSCI_FW) guard either
(as long as the code still compiles fine when that config option is
disabled), and you wouldn't need those dummy callbacks.

Cheers,

Slightly more complex case, but looks fine to me.
