PSCI: Demonstrate support for composite power states

This patch adds support to the Juno and FVP ports for composite power states
with both the original and extended state-id power-state formats. Both the
platform ports use the recommended state-id encoding as specified in
Section 6.5 of the PSCI specification (ARM DEN 0022C). The platform build flag
ARM_RECOM_STATE_ID_ENC is used to include this support.

By default, to maintain backwards compatibility, the original power state
parameter format is used and the state-id field is expected to be zero.
