arm64: cputype: Add C1-Premium definitions
Add cputype definitions for C1-Premium. These will be used for errata
detection in subsequent patches.
These values can be found in the C1-Premium TRM:
https://developer.arm.com/documentation/109416/0100/
... in section A.5.1 ("MIDR_EL1, Main ID Register").
