Convert existing binding to dtschema to support validation.

This is a direct conversion with no additions.

This is not correct because at least start-year is supported. Please
check for all your other submissions too.

allOf:
  - $ref: rtc.yaml#

is missing, and then

unvealuatedProperties: false

to account for that.

"start-year" is read in the RTC base class, so I wonder why so many RTC
bindings add a reference to rtc.yaml, but then use

additionalProperties: false

They may have pre-dated support for 'unevaluatedProperties', or you can 
list out which properties are used from a referenced schema which 
disallows unlisted properties. There's no hard rule here. Either way is 
fine.

Other than this and my 1 other comment, this series looks fine to me.
