Add binding for the TI's sdhci-omap controller. This now includes only
a subset of properties documented in ti-omap-hsmmc.txt but will eventually
include all the properties.

Changes from v1:
*) Create a new sdhci-omap.txt document for TI's sdhci-omap controller instead
   of using the ti-omap-hsmmc.txt as suggested by Tony

+* TI OMAP SDHCI Controller
+
+Refer to mmc.txt for standard MMC bindings.
+
+Required properties:
+- compatible: Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers
+- ti,hwmods: Must be "mmc<n>", <n> is controller instance starting 1
+
+Optional properties:
+- ti,dual-volt: boolean, supports dual voltage cards
+- ti,non-removable: non-removable slot (like eMMC)
+
+Example:
+	mmc1: mmc@0x4809c000 {
+		compatible = "ti,omap4-hsmmc";
+		reg = <0x4809c000 0x400>;
+		ti,hwmods = "mmc1";
+		ti,dual-volt;
+		bus-width = <4>;
+		vmmc-supply = <&vmmc>; /* phandle to regulator node */
+		ti,non-removable;
+	};
