After this series, the plan is to convert the last in-tree user
of the private EDMA API (davinci-pcm/mcasp) and then eliminate
the private EDMA API by folding its functionality into
drivers/dma/edma.c.

This patch updates the mcasp clock entries so clk_get() will succeed.
It is tested on BeagleBone and is needed for 3.7-rc1 to fix AM33xx
boot.

Fix build on OMAP, the irqs are undefined on AM33xx.
These error interrupt handlers were hardcoded as disabled

The davinci-pcm driver is the last in-kernel user of the private
EDMA API. Once it has been converted to DMA Engine API the
private EDMA API functionality can be folded into the EDMA DMA
Engine driver and removed.

For platforms with DT populated, use dma_request_slave_channel()
to acquire the DMA channel. For !DT platforms, we fall back to
explicitly passing the omap_dma_filter_fn() to dma_request_channel().
Once all platforms boot from DT, the dma_request_channel() path can
be dropped.

Enable pinctrl dummy states for all OMAP platforms that don't
populate DT. This allows drivers to be converted to pinctrl
and not generate new warnings on platforms that do not provide
pinctrl data. These platforms already have pinmuxes configured
before the drivers probe.

pinctrl to set pinmuxes appropriately require this
for omap2-mcspi operation.
It has been tested on AM335x BeagleBone with an Adafruit SPI LCD attached
and regression tested on Beagleboard xM booting in the !DT case, using
board-omap3evm.c.
The series applies on top of Tony's dt-devel branch.
