arm64: cputype: Add Cortex-A720 definitions
[ Upstream commit add332c40328cf06fe35e4b3cde8ec315c4629e5 ]
Add cputype definitions for Cortex-A720. These will be used for errata
detection in subsequent patches.
These values can be found in Table A-186 ("MIDR_EL1 bit descriptions")
in issue 0002-05 of the Cortex-A720 TRM, which can be found at:
