refactor(cpus): rename errata_report.h to errata.h

The ERRATA_XXX macros, used in cpu_helpers.S, are necessary for the
check_errata_xxx family of functions. The CPU_REV should be used in the
cpu files but for whatever reason the values have been hard-coded so far
(at the cost of readability). It's evident this file is not strictly for
status reporting.

The new purpose of this file is to make it a one-stop-shop for all
things errata.
