ARM errata: Cache maintenance by set/way operations can execute out of order

configname: CONFIG_ARM_ERRATA_814220

└─> ARM errata: Cache maintenance by set/way operations can execute out of order

The v7 ARM states that all cache and branch predictor maintenance
operations that do not specify an address execute, relative to
each other, in program order.
However, because of this erratum, an L2 set/way cache maintenance
operation can overtake an L1 set/way cache maintenance operation.
This ERRATA only affected the Cortex-A7 and present in r0p2, r0p3,
r0p4, r0p5.
