[PATCH v3 0/4] dt-bindings: rtc: ti,omap-rtc: Convert to DT schema and cleanups

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

The am3352-rtc is compatible with the da830-trc. Update the compatible
string to include the ti,da830-rtc fallback 

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.

Changes in v3:
- fixed dts where only am3352-rtc was used without da830-rtc
- fixed compatible where am3352 is only compatible with da830
- simplified clock-output-names property and pins property
- Link to v2: https://lore.kernel.org/r/[email protected]

Changes in v2:
- Patch 1: unchanged
- Patch 2: unchanged
- Patch 3: Removed left out legacy text binding and Added constraint
  block restricting 'system-power-controller' and 'ext-wakeup' subnodes
  strictly to hardware variants that support PMIC mode
