Fix broken standby state implementation in PSCI
This patch fixes the broken support for entry into standby states introduced under commit-id 'd118f9f864' (tf-issues#94). Upon exit from the platform defined standby state instead of returning to the caller of the SMC, execution would get stuck in the wfi instruction meant for entering a power down state. This patch ensures that exit from a standby state and entry into a power down state do not interfere with each other. Fixes ARM-software/tf-issues#154 Change-Id: I56e5df353368e44d6eefc94ffedefe21929f5cfe
