This patch enables the workaround for ARM errata 798870 for OMAP5 / DRA7 which says "If back-to-back speculative cache line fills (fill A and fill B) are issued from the L1 data cache of a CPU to the L2 cache, the second request (fill B) is then cancelled, and the second request would have detected a hazard against a recent write or eviction (write B) to the same cache line as fill B then the L2 logic might deadlock."
An l2auxctlr accessor implementation for OMAP5 and DRA7 is introduced here as well.
