arm64: cputype: Add Cortex-A725 definitions
[ Upstream commit 9ef54a384526911095db465e77acc1cb5266b32c ] Add cputype definitions for Cortex-A725. These will be used for errata detection in subsequent patches. These values can be found in the Cortex-A725 TRM: https://developer.arm.com/documentation/107652/0001/ ... in table A-247 ("MIDR_EL1 bit descriptions").
