Subject: [PATCH] arm64: alternative: Always emit the first instruction in
 ALTERNATIVE blocks

Currently with the ALTERNATIVE macro or alternative_insn, the cfg (or
enable) arguments disable the entire asm block. Change the macros to
only omit the alternative block on !IS_ENABLED(cfg). In addition, remove
the cfg arguments to to ALTERNATIVE in those few calls where it is still
passed. There is no change to the resulting kernel image with defconfig.

alternative_insn's enable argument will be used in a subsequent patch
and we are keeping the ALTERNATIVE C macro arguments in line with the
asm version.

I no longer need this patch as I moved the page tag zeroing from
clear_page to the actual mte.S file (called via set_pte_at()). So don't
bother reviewing this.
