Rework the PSCI migrate APIs
This patch reworks the PSCI MIGRATE, MIGRATE_INFO_TYPE and
MIGRATE_INFO_UP_CPU support for Trusted Firmware. The
implementation does the appropriate validation of parameters
and invokes the appropriate hook exported by the SPD.
The TSP is a MP Trusted OS. Hence the ability to actually
migrate a Trusted OS has not been implemented. The
corresponding function is not populated in the spd_pm_hooks
structure for the TSPD.
The `spd_pm_ops_t` has undergone changes with this patch.
SPD PORTS MAY NEED TO BE UPDATED.
Fixes ARM-software/tf-issues#249
