dt-bindings: power: reset: ti,keystone-reset: Convert to DT schema

This commit converts the Texas Instruments Keystone SoC Reset Controller
binding from a text document to a DT schema. The commit message notes
there are no new functional changes.

[Severity: Medium]
Does adding 'reg' to the required list break backward compatibility with
existing device trees?

The old text binding did not document or include a 'reg' property in its
examples, meaning existing device trees following the old binding will now
fail validation during `make dtbs_check` with this new schema. Since the
kernel driver does not parse or map the 'reg' property and relies on syscon
offsets instead, is it necessary to mark 'reg' as strictly required here?
