arm64: cputype: Add Cortex-X3 definitions

Browse source 
[ Upstream commit be5a6f2387 ]

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:
