I didn't see at first why this is unused, but eventually figured out
that it's because
all ARMv6+ platforms use CONFIG_GENERIC_IRQ_MULTI_HANDLER,
the last one that provided a custom test_for_ipi was removed in 2015
with commit 59b89af1d555 ("ARM: shmobile: sh7372: Remove Legacy C
SoC code").

FWIW, the only remaining platforms with a custom entry-macro.S are rpc,
iop320 and footbridge.
