dra7: mmc: Update mmc dt node to use sdhci-omap

Changes from v3:
*) Added dra7-mmc-iodelay.dtsi to add a new pinctrl group for clk line
without pullup to be used for dra71-evm and am57xx-idk.
*) Rename wlcore node name to wifi

This series should be merged only after [1].

This series:
*) Adds wilink wlan support (Now all MMC instances in DRA7 will use
sdhci-omap)
*) Add a new pinctrl group for clk line without pullup required for
UHS cards to work reliably.
*) Update README to make sure users update .config file from 4.18
kernel.
*) Use sdhci-omap programming model.

In the "Use sdhci-omap programming model" patch, "ti,omap4-hsmmc" compatible is removed. This is because if both "ti,dra7-sdhci" and "ti,omap4-hsmmc" is added and if there is probe deferral in sdhci_omap driver, the device is binding to omap_hsmmc driver.

Once omap_hsmmc and sdhci_omap driver are feature identical, sdhci_omap driver will be made to support omap_hsmmc binding (including "ti,omap4-hsmmc" compatible) and omap_hsmmc driver will be removed. Till then dt nodes with "ti,omap4-hsmmc" compatible will use omap_hsmmc driver and "ti,dra7-sdhci" compatible will use sdhci_omap driver.
