My opinion is that SPARSE_IRQ shouldn't be user visible option, and the
simple solution was to just make it hidden. It wasn't clear if this was
desired or not for other arches at the time. There is a mixture of
settings in powerpc defconfigs. SuperH selects it for 32-bit and leaves
it user selectable for 64-bit.

I'm happy to revert adding MAY_HAVE_SPARSE_IRQ and just make SPARSE_IRQ
a hidden option. It really just needs the okay from SuperH folks.
