feat(plat/sgi): enable use of PSCI extended state ID format

The SGI/RD platforms have been using PSCI state ID format as defined in
PSCI version prior to 1.0. This is being changed and the PSCI extended
state ID format as defined in PSCI version 1.1 is being adapted. In
addition to this, the use of Arm recommended PSCI state ID encoding is
enabled as well.
