remove frv usage of flush_tlb_pgtables()
frv is the last user in the tree of that dubious hook, and it's my understanding that it's not even needed. It's only called by memory.c free_pgd_range() which is always called within an mmu_gather, and tlb_flush() on frv will do a flush_tlb_mm(), which from my reading of the code, seems to do what flush_tlb_ptables() does, which is to clear the cached PGE.
