[v3,2/3] ARM: OMAP2+: L2 cache: git rid of redundant cache replacement policy setting

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.
