This patch implements a set of handlers in the SPD which are called by the PSCI runtime service upon receiving a power management operation. These handlers in turn pass control to the Secure Payload image if required before returning control to PSCI. This ensures that the Secure Payload has complete visibility of all power transitions in the system and can prepare accordingly. Change-Id: I2d1dba5629b7cf2d53999d39fe807dfcf3f62fe2
