arm64: cputype: Add Neoverse-V3AE definitions
commit 3bbf004c4808e2c3241e5c1ad6cc102f38a03c39 upstream.
Add cputype definitions for Neoverse-V3AE. These will be used for errata
detection in subsequent patches.
These values can be found in the Neoverse-V3AE TRM:
https://developer.arm.com/documentation/SDEN-2615521/9-0/
... in section A.6.1 ("MIDR_EL1, Main ID Register").
