[PATCH v4 1/8] arm64: Set CONFIG_MULTI_IRQ_HANDLER

[Palmer Dabbelt]

arm has an optional MULTI_IRQ_HANDLER, which arm64 copied but didn't
make optional.  I'm converting this to generic code, but in order to
ensure everything stays bisectable I want this defined on arm64 for now.
This will go away by the end of the patch set.
