[ARM] Feroceon: speed up flushing of the entire cache
Flushing the L1 D cache with a test/clean/invalidate loop is very easy in software, but it is not the quickest way of doing it, as there is a lot of overhead involved in re-scanning the cache from the beginning every time we hit a dirty line. This patch makes proc-feroceon.S use "clean+invalidate by set/way" loops according to possible cache configuration of Feroceon CPUs (either direct-mapped or 4-way set associative).
