irqchip: omap-intc: Fix legacy DMA regression
commit 55601c9f2467 (arm: omap: intc: switch over
to linear irq domain) introduced a regression with
SDMA legacy driver because that driver strictly depends
on INTC's IRQs starting at NR_IRQs. Aparently
irq_domain_add_linear() won't guarantee that, since we see
a 7 IRQs difference when booting with and without the
commit cited above.
Until arch/arm/plat-omap/dma.c is properly fixed, we
must maintain OMAP2/3 using irq_domain_add_legacy().
A FIXME note was added so people know to delete that
code once that legacy DMA driver is fixed up.
