[PATCH] Add Broadcom Brahma-B53 CPU implementor and part number

Broadcom's Brahma-B53 CPU features a PMU which is 100% software
compatible with those found on Cortex-A53 designs. Add the required
code to recognize the implementor id (0x42) and the Brahma-B53 part
number (0x100) and return "arm/armv8-ca53" so we can utilize the PMU.
