arm64: mm: Refactor flush_tlb_page() to use __tlbi_level_asid()

Browse source

Now that we have __tlbi_level_asid(), let's refactor the
*flush_tlb_page*() variants to use it rather than open coding.

The emitted tlbi(s) is/are intended to be exactly the same as before; no
TTL hint is provided. Although the spec for flush_tlb_page() allows for
setting the TTL hint to 3, it turns out that
flush_tlb_fix_spurious_fault_pmd() depends on
local_flush_tlb_page_nonotify() to invalidate the level 2 entry. This
will be fixed separately.
