These are needed only for dma because mach-omap2/dma.c still creates
devices from hmwod and which are used by plat/dma.c.
These irqs for sdma exist even in the cleaned up omap4 and omap5 hmwod files.
I'll try and get rid of that dependency of plat/dma on mach/dma to create devices.

We already have irq/dma and iospace moved to DT (some iospace info still
exists because of non-DT drivers). With Teros patches to move clock data we
should be able to pass the main_clk and all interface level clock info too
from DT.
