Patrick Delaunay 1a047c23f9 arm: psci: save context id for cpu_on PSCI command 
Save and use the 3rd parameter of PSCI CPU_ON request: context_id.

The context_id parameter is only meaningful to the caller.
U-Boot PSCI preserves a copy of the value passed in this parameter.
Following wakeup from a  powerdown state, U-BOOT PSCI places
this value in R0 when it first enters the OS.

NB: this context id is not (yet?) used by Linux but it is mandatory
    to be PSCI compliant.

update armv7 psci functions:
- psci_save_target_pc(): keep for backward compatibility with
  current platform (only save PC and force context id to 0)
  => should be removed when all platform migrate to the new API

- psci_save(): new API to use by ARMv7 platform with PSCI,
  save pc (= entry_point_address) and context_id
