ARM: fix ifdefs in ARMv8 lowlevel_init()
Commit 724219a65f55 "ARM: always perform per-CPU GIC init" removed some ifdefs to unify the MULTIENTRY-vs-non-MULTIENTRY paths. However, the wrong endif was removed. This patch adds back that missing endif, and adds a new ifdef to match the endif the now-correctly-terminated block used to match against. Use "git show -U25 724219a65f55" to see enough context to make the original issue clear. In practical terms, this makes no difference to runtime behaviour. The code that was incorrectly compiled into the binary when ifndef MULTIENTRY is a no-op for other cases, since branch_if_master evaluates to a hard- coded jump. The only issues were: - A few extra instructions were added to the binary. - The comment on the endif at the very end of the function, indicating which ifdef it matched, were wrong. An alternative might be to simply fix the comment on that trailing ifdef, but that only addresses the second point above, not the first.
