[ARM] 5192/1: ARM TLB: add v7wbi_{possible,always}_flags to {possible,always}_tlb_flags
Commit 2ccdd1e77da52ad494e9af46bf272d816830cb28 doesn't add v7wbi_possible_flags and v7wbi_always_flags to possible_tlb_flags and always_tlb_flags. This causes the L2 cache flush in clean_pmd_entry() (intended for Feroceon only) to execute on ARMv7, and the CPU hangs. This patch is required for OMAP3 boards to boot.
