Subject: [PATCH] ARC: remove checks for CONFIG_ARC_MMU_V4

There's no Kconfig symbol ARC_MMU_V4 so the checks for CONFIG_ARC_MMU_V4
will always evaluate to false. Remove them.

Entirely untested!

It would be nice if this could be squashed into commit ef680cdc2437
("ARC: Disable caches in early boot if so configured"). But I guess the
ARC tree that is included in linux-next cannot be rebased.
