arm64: add mpidr field to cpu_info struct
The cpu_info struct can be easily obtained at runtime
based on smp_processor_id(). To allow easier mapping
between cpu_info and PSCI entities add the mpidr info
to the cpu_info struct.
BUG=chrome-os-partner:32136
BRANCH=None
TEST=Built and booted in SMP. Noted MPIDR messages for each cpu.
