Device tree changes for omap variants for SDHCI

This series adds the devicetree configuration needed for pinctrl on
dra7 variants to use the SDHCI SDIO driver instead of mmc-omap-hs
driver. To use SDHCI, both the pins and the iodelay needs to be
configured.

This series is based on the related SDHCI drivers changes on a branch
set up by Ulf.
