[PATCH 1/2] ARM: mx28: Add SPI pinmux into imx28.dtsi

[Marek Vasut]

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?
