It appears arm64 copied arm's GENERIC_IRQ_MULTI_HANDLER code, but made
it unconditional. I wanted to make this generic so it could be used by
the RISC-V port. This patch converts the arm64 code to use the new
generic code, which simply consists of deleting the arm64 code and
setting MULTI_IRQ_HANDLER instead.
