arm64: cputype: Add C1-Ultra definitions

Add cputype definitions for C1-Ultra. These will be used for errata
detection in subsequent patches.

These values can be found in the C1-Ultra TRM:

  https://developer.arm.com/documentation/108014/0100/

... in section A.5.1 ("MIDR_EL1, Main ID Register").
