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.

Changes in v3:
- Check the major revision of Cortex-A53.
Changes in v2:
- Check the revision of Cortex-A53 and apply the erratum to r0p3 and later release.
- Fix the mistake in the commit description.
Applied to fsl-qoriq master. Thanks.
Just a note if this is just for a53 should we consider to place these Kconfigs to arch/arm/cpu/armv8/Kconfig?
We were following Tom Rini's move in commit 8dda2e2f9. I am not against moving ARMv8 related config options, if no single erratum applies to both ARMv8 and legacy cores.
ok. Good.
Thanks, Michal
