[PATCH] ARM: at91/dt: add pullup on mmc2 data signals

[nicolas.ferre@atmel.com (Nicolas Ferre)]

> MMC data lines may be left floating if nothing is currently driving the
> data lines, which is the case when mmc is in idle state, thus consuming
> a useless extra amount of power. Add pullup on mmc2 data signals in the
> same way it was previously done for mmc0 and mmc1.
