ARC: remove checks for CONFIG_ARC_MMU_V42014-06-16T06:04:29ZPaul Bollepebolle@tiscali.nl2014-06-11T08:57:50Zurn:sha1:230a15f171ba24226486664fc44542b175107ab7
There's no Kconfig symbol ARC_MMU_V4 so the checks for CONFIG_ARC_MMU_V4
will always evaluate to false. Remove them.

Having them be different seems an obscure configuration.

to cross check with with built-in constants
* Use of IS_ENABLED() to check for a Kconfig option

* ARC700 has VIPT L1 Caches
* Caches don't snoop and are not coherent
* Given the PAGE_SIZE and Cache associativity, we don't support aliasing
D$ configurations (yet), but do allow aliasing I$ configs
