arm64: cputype: Add missing MIDR values for Cortex-A72 and Cortex-A75 




From: Will Deacon <will.deacon@arm.com>

commit a65d219fe5dc7887fd5ca04c2ac3e9a34feb8dfc upstream.

Hook up MIDR values for the Cortex-A72 and Cortex-A75 CPUs, since they
will soon need MIDR matches for hardening the branch predictor.
