It is not good to have cpu_name and to_version encoded into sdma
firmware name as variables.  For example, there are three TOs of
imx51 soc, the sdma script never changes since TO1, which means
all three TOs of imx51 uses TO1 version of sdma script.  But we
have to prepare three identical firmwares, sdma-imx51-to1.bin
sdma-imx51-to2.bin and sdma-imx51-to3.bin, to have the kernel
capable of running on all three TOs.

The patch removes cpu_name and to_version from sdma platform data,
and instead uses fw_name to pass the firmware name, so that we can
pass the TO version where it's relevant and skip it where only one
firmware exists.

The patch follows the implementation of gpio-mxc device registration
to break the concentrated imx-dma device registration into soc
specific setup function.  Then we can avoid the churn of "#ifdef"
and the cpu_is_mx checking on such a long list, which makes no sense,
considering more soc supports need to be added and we need to support
single image for multiple socs in the long run.

On the i.MX SPI driver the chipselect pins can be of the following types:

- internal: when the chipselect pin is used as a dedicated CS pin of the CSPI controller
- GPIO: a generic GPIO can be used as a chipselect funtion

On the mx27_3ds the SPI2 chip select is a GPIO, so don't annotate 'internal' in the chip select
definition.
