Flat irq_desc[] is simple and easy for debugging. We do want to del it?
This patches want to kill MAY_HAVE_SPARSE_IRQ, not !SPARSE_IRQ.
so I won't delete above parts(eg, ARM could use both SPARSE_IRQ and
!SPARSE_IRQ via different config,)

Most ARCHs support SPARSE_IRQ, and MAY_HAVE_SPARSE_IRQ is useless, and
only sh and csky select it, but the could use SPARSE_IRQ too, let's
kill MAY_HAVE_SPARSE_IRQ, also cleanup the kernel/irq/Kconfig a little.

sh: Cleanup about SPARSE_IRQ
csky: Use SPARSE_IRQ
genirq: Cleanup Kconfig
