armv8: errata: Implement workaround for Cortex-A53 Erratum 855873
855873: An eviction might overtake a cache clean operation
Workaround: The erratum can be avoided by upgrading cache clean by
address operations to cache clean and invalidate operations. For
Cortex-A53 r0p3 and later release, this can be achieved by setting
CPUACTLR.ENDCCASCI to 1.
This patch is to implement the workaround for this erratum.
