ARM: cache-l2x0: update workaround for PL310 errata 727915
ARM errata 727915 for PL310 has been updated to include a new
workaround required for PL310 r2p0 for l2x0_flush_all, which also
affects l2x0_clean_all in my testing. For r2p0, clean or flush
each set/way individually. For r3p0 or greater, use the debug
register for cleaning and flushing.
Requires exporting the cache_id, sets and ways detected in the
init function for later use.
