It has been reported that the overhead of repeating all TLBI
instructions is too large [1]. The Software Developer Errata Notices
(SDEN) for the relevant Arm CPUs have been updated so a single
"tlbi vale1is, xzr" followed by "dsb ish" is sufficient to work around
the issues.
Replace the places we repeat TLBI instructions with the new sequence.
