Subject: [PATCH v3 2/4] dt-bindings: rtc: convert trivial devices into
dtschema
These RTCs meet the requirements for a direct conversion into
trivial-rtc:
- google,goldfish-rtc
- maxim,ds1742
- lpc32xx-rtc
- orion-rtc
- rtc-aspeed
- spear-rtc
- via,vt8500-rtc

dt-bindings: rtc: lpc32xx-rtc: convert to dtschema
Convert existing binding to dtschema to support validation.
Add the undocumented 'clocks' property.
