[PATCH 87/97] ARM: l2c: omap2+: get rid of redundant cache replacement policy setting

From: Sekhar Nori <nsekhar@ti.com>
To: linux-arm-kernel@lists.ifradead.org

L2 cache initialization for OMAP4 redundantly sets the cache policy to
Round-Robin. This is not needed since thats the PL310 default anyway.

Removing this reduces the number of platform specific aux control
settings.
