arm64: cputype: Add Cortex-X1C definitions
[ Upstream commit 58d245e03c324d083a0ec3b9ab8ebd46ec9848d7 ]
Add cputype definitions for Cortex-X1C. These will be used for errata
detection in subsequent patches.
These values can be found in the Cortex-X1C TRM:
https://developer.arm.com/documentation/101968/0002/
... in section B2.107 ("MIDR_EL1, Main ID Register, EL1").
