[PATCH 3/4] arm64: cputype: Add Neoverse-V3 definitions

[Mark Rutland]

Add cputype definitions for Neoverse-V3. These will be used for errata
detection in subsequent patches.

These values can be found in Table B-249 ("MIDR_EL1 bit descriptions")
in issue 0001-04 of the Neoverse-V3 TRM, which can be found at:
