From: David Woodhouse <dwmw@xxxxxxxxxxxx> The v1.3 PSCI spec (https://developer.arm.com/documentation/den0022) adds SYSTEM_OFF2, CLEAN_INV_MEMREGION and CLEAN_INV_MEMREGION_ATTRIBUTES functions. Add definitions for them and their parameters, along with the new TIMEOUT, RATE_LIMITED and BUSY error values.
