ARM: 9133/1: mm: proc-macros: ensure *_tlb_fns are 4B aligned
commit e6a0c958 upstream. A kernel built with CONFIG_THUMB2_KERNEL=y and using clang as the assembler could generate non-naturally-aligned v7wbi_tlb_fns which results in a boot failure. The original commit adding the macro missed the .align directive on this data.
