So we need to make all arches support SPARSE_IRQ at first?

Now we have arm, arm64, c6x, metag, powerpc, sh, x86 support SPARSE_IRQ.

The following are not with SPARSE_IRQ yet:
alpha, arc, avr32, blackfin, cris, frv, hexagon, m32r, m68k, microblaze,
mips, mn10300, openrisc, parisc, s390, score, sparc, tile, um,
unicore32, xtensa.

Thanks
