ARM platforms: Add support for MT bit in MPIDR
This patch modifies some of the functions in ARM platform layer to cater for the case when multi-threading `MT` is set in MPIDR. A new build flag `ARM_PLAT_MT` is added, and when enabled, the functions accessing MPIDR now assume that the `MT` bit is set for the platform and access the bit fields accordingly. Also, a new API plat_arm_get_cpu_pe_count is added when `ARM_PLAT_MT` is enabled, returning the PE count within the physical cpu corresponding to `mpidr`.
