Subject: [PATCH 0/2] Advertise pm_resume/suspend_via_firmware with PSCI

Some device drivers are curious to know if "the firmware" (which to many
just means ACPI, because x86/ibm_pc is clearly the only arch on this
planet :P) is responsible for suspending/resuming the platform, altering
their behavior if that's the case.

The same flag makes sense regardless of the type of firmware used. PSCI
also happens to be the suspend handler on many platforms even without
ACPI, so it's only natural to report such capabilities as well.
