Add this SSP pin multiplexing configuration into the imx28.dtsi file.
This covers pinmux for all four SSP ports available on the i.MX28.

NOTE: Shawn, I'd like to add this altogether. I have a board scheduled in my
queue that uses other SSP ports, so I consider it pointless to split this.
Fabio, what does MX28EVK use?

So we will probably need to have the group only define SS0 and set up the extra SS in board's hog node, so that the group can be shared across more boards. Or, we name the group spi2_3cs_pins_a and leave the name spi2_pins_a to the more general case, one SS?
