[PATCH 1/5] arm64: cputype: Add Cortex-X3 definitions

[Mark Rutland]

Add cputype definitions for Cortex-X3. These will be used for errata
detection in subsequent patches.

These values can be found in Table A-263 ("MIDR_EL1 bit descriptions")
in issue 07 of the Cortex-X3 TRM, which can be found at:
