spi: mxs-spi: move to use generic DMA helper
...
With the generic DMA device tree helper supported by mxs-dma driver,
client devices only need to call dma_request_slave_channel() for
requesting a DMA channel from dmaengine.
Since mxs is a DT only platform now, along with the changes, the non-DT
case handling in probe function also gets removed.

mmc: spi: Rename IMX2[38]_MMC to IMX2[38]_SSP
...
Since the SSP controller can act as both SPI and MMC host,
renaming the enum to properly reflect the naming seems
appropriate.

mmc: spi: Move SSP register definitions into separate file

Move the definitions into separate file so separate SPI driver can be
implemented. The SSP controller in MXS can act both as a MMC host and
as a SPI host.
