[PATCH 1/2] dt-bindings: Renesas versaclock7 device tree bindings

[Alex Helms <alexander.helms.jy@renesas.com>]

Renesas Versaclock7 is a family of configurable clock generator ICs
with fractional and integer dividers. This driver has basic support
for the RC21008A device, a clock synthesizer with a crystal input and
8 outputs. The supports changing the FOD and IOD rates, and each
output can be gated.
