[PATCH 15/17] arm64/mm: Add an abstraction level for tlbi_op

[Anshuman Khandual <anshuman.khandual@arm.com>]

From: Linu Cherian <linu.cherian@arm.com>

With FEAT_D128, a new instruction aka TLBIP is being introduced for the TLB
-by-range operations which has an argument size of 128 bit.

Add an abstraction level to void (*tlbi_op)(u64 arg) helpers to support the
D128 variations when applicable.

No functional changes are introduced with this patch.
