Subject: ACPI / APEI: Remove arch_apei_flush_tlb_one()

From: James Morse <james.morse@arm.com>

commit 4a75aeacda3c2455954596593d89187df5420d0a upstream.

Nothing calls arch_apei_flush_tlb_one() anymore, instead relying on
__set_pte_vaddr() to do the invalidation when called from clear_fixmap()
Remove arch_apei_flush_tlb_one().

it included in the stable tree.
