ARM: OMAP2+: Drop sdma interrupt handling for mach-omap2

Browse source

All device tree probing omap SoCs only have device drivers that are using
Linux dmaengine API with the IRQENABLE_L1 interrupts. Only omap1 is still
using old legacy dma.

This means we can remove the legacy sdma interrupt handling for
IRQENABLE_L0, and only rely on the dmaengine driver using IRQENABLE_L1.

The legacy code still allocates the channels, but that will be deal with
in the following patches.
