[PATCH 1/3] arm64: Set CONFIG_MULTI_IRQ_HANDLER

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 aid the porting effort I want to define this on arm64 for a bit. This will go away at the end of this patch set. Signed-off-by: Palmer Dabbelt
