Subject: [PATCH v2] dt-bindings: arm: vt8500: Add VIA APC Rock/Paper boards

APC Rock is a development board based on WonderMedia WM8950 SoC
released around 2013. Paper is the same as Rock but lacking a
VGA port and shipped with a recycled cardboard case.

While at that, put myself as the maintainer, given that Tony is
unavailable as of lately.

Split the series from v1 into separate bindings patches so as not to
spam all the subsystems with unrelated changes, per Rob's suggestion

Changes in v2:
- kept single-valued compatibles in a single enum (thanks Rob)
- dropped the empty overall description node
