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 MX1, MX21 and MX27 each GPIO port has an address space of 256 bytes.

Fix the iosize for these platforms.

Tested on a mx27_3ds board that can boot fine after this change.

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.
