PSCI v1.0 augmented the power_state parameter format specification (extended stateid) and introduced a way to probe it through the PSCI_FEATURES interface. This patch implements code that detects the power_state format at run-time through the PSCI_FEATURES interface, so that the power_state argument can be properly detected and validated in the kernel according to the information provided through firmware.
