* Firmware components like SPD using the old platform API to work.
* This API is deprecated and it assumes that the mpidr specified is
* that of a valid and present CPU. Instead, plat_my_core_pos()
* should be used for CPU index of the current CPU and
* plat_core_pos_by_mpidr() should be used for CPU index of a
