arm64: cputype: Add Cortex-X3 definitions

[ Upstream commit be5a6f238700f38b534456608588723fba96c5ab ]

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:
