This should be same as flush_tlb_page except for hash32. For hash32
I guess the existing code is wrong, because we don't seem to be
flushing tlb for Hash != 0 case at all. Fix this by switching to
calling flush_tlb_page() which does the right thing by flushing
tlb for both hash and nohash case with hash32

Core kernel doesn't track the page size of the VA range that we are
invalidating. Hence we end up flushing TLB for the entire mm here. Later
patches will improve this.
We also don't flush page walk cache separetly instead use RIC=2 when
flushing TLB, because we do a MMU gather flush after freeing page table.
MMU_NO_CONTEXT is updated for hash.
