[PATCH v2 1/2] arm64: Add CPU part numbers for newer Apple Silicon CPUs

[Michael Reeves via B4 Relay]

From: Myria Sarvay <myrialsarvay@xxxxxxxxx>

Add CPU part numbers and MIDR definitions for M3, M3 Pro, M3 Max,
base M4, A18 Pro and M5 Pro so CPU workarounds can identify these cores.

Use the SoC codenames for M4, A18 Pro and M5 Pro, with suffixes for
their core types, as separate core codenames are not known.
