ARM: Fix errata 411920 workarounds
Errata 411920 indicates that any "invalidate entire instruction cache"
operation can fail if the right conditions are present. This is not
limited just to those operations in flush.c, but elsewhere. Place the
workaround in the already existing __flush_icache_all() function
instead.
