[PATCH 5.15.y 09/14] arm64: cputype: Add Cortex-X925 definitions

[ Upstream commit fd2ff5f0b320f418288e7a1f919f648fbc8a0dfc ]

Add cputype definitions for Cortex-X925. These will be used for errata detection in subsequent patches.

These values can be found in Table A-285 ("MIDR_EL1 bit descriptions") in issue 0001-05 of the Cortex-X925 TRM, which can be found at:
