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 v2:
*) Fixed example to use the updated compatible
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,dra7-sdhci";
+ reg = <0x4809c000 0x400>;
+ ti,hwmods = "mmc1";
+ ti,dual-volt;
+ bus-width = <4>;
+ vmmc-supply = <&vmmc>; /* phandle to regulator node */
+ ti,non-removable;
+ };
