drivers: firmware: psci: add INVALID_ADDRESS return value
PSCI 1.0 introduces the INVALID_ADDRESS return value for functions that take an address as input parameter (eg CPU_SUSPEND). This patch adds INVALID_ADDRESS return value to kernel code and updates the PSCI to linux error conversion to take it into account. The kernel error value associated to INVALID_ADDRESS is set to the error returned when the PSCI error code is INVALID_PARAMETERS to comply with current call sites expected return value, given that the kernel at present has no use for the additional error information reported.
