ARM: nomadik: fix up SD/MMC DT settings
The DTSI file for the Nomadik does not properly specify how the PL180 levelshifter is connected: the Nomadik actually needs all the five st,sig-dir-* flags set to properly control all lines out. Further this board supports full power cycling of the card, and since this variant has no hardware clock gating, it needs a ridiculously low frequency setting to keep up with the ever overflowing FIFO. The pin configuration set-up is a bit of a mystery, because of course these pins are a mix of inputs and outputs. However the reference implementation sets all pins to "output" with unspecified initial value, so let's do that here as well.
