MAINTAINERS: drop entry to removed file in ARM/RISCPC ARCHITECTURE

Commit c1fe8d0 ("ARM: riscpc: use GENERIC_IRQ_MULTI_HANDLER") removes
arch/arm/include/asm/hardware/entry-macro-iomd.S, but missed to adjust
MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Drop the file entry to the removed file in ARM/RISCPC ARCHITECTURE.
