This series converts the Texas Instruments OMAP Real Time Clock (RTC) 
binding from the legacy format to dt-schema.

During the conversion process, two legacy, undocumented properties 
were discovered in the upstream device trees:
 - 'ext-clk-src' in am57xx-idk-common.dtsi
 - 'ti,no-init' in am335x-shc.dts

Both properties are completely unhandled by the rtc-omap driver. Patches
1 and 2 remove them from the device trees. Patch 3 then introduces the
new YAML schema.
