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:

... in section A.6.1 ("MIDR_EL1, Main ID Register").
