OMAP1 does not use DT. So we could put this code under #ifdef
CONFIG_ARCH_OMAP1 or similar. It's just a few lines of code. OMAP2+
work should not regress OMAP1.

Demanding SPARSE_IRQ support for OMAP1 should have been discussed before
these changes were made. It's not reasonable to assume such things can
be made during rc-cycle. Also, now, I don't think it's reasonable to
wait for that to be done, as it would take until 3.12 or even later to
get OMAP1 functional again.
