[ARM] 4135/1: Add support for the L210/L220 cache controllers This patch adds the support for the L210/L220 (outer) cache controller. The cache range operations are done by index/way since L2 cache controller only accepts physical addresses.

ARM: 6094/1: Extend cache-l2x0 to support the 16-way PL310 The L310 cache controller's interface is almost identical to the L210. One major difference is that the PL310 can have up to 16 ways. This change uses the cache's part ID and the Associativity bits in the AUX_CTRL register to determine the number of ways. Also, this version prints out the CACHE_ID and AUX_CTRL registers.
