This series adjusts the IMX serial and GPIO drivers to support driver model.
As an example of its use, the recently-added cm_fx6 board is converted over
to driver model.
Some minor driver model core changed are required to make this work and
these are included with this series.
Thanks to the Compulab people for helping with this.
Changes in v4:

Adjust error checking to permit calling gpio_request() multiple times
Avoid doing low-level SATA init multiple times
Move SATA changes into the next patch
Move SATA changes into this patch

Hopefully this is closer. I found out why I couldn't do what I
suggested for the gpio_request() handling. It seems easier to check
for -EBUSY. Feel free to adjust these patches as you wish - I was
planning on pushing them to dm/next when ready.

Simon
