Subject: [PATCH v2 1/3] dt-bindings: arm: google: add gs101-raven and
 generic gs101-pixel

Raven is Google's code name for Pixel 6 Pro. Since there are
differences compared to Pixel 6 (Oriole), we need to add a separate
compatible for it.

We also want to support a generic DT, which can work on any type of
gs101-based Pixel device, e.g. Pixel 6, or Pixel 6 Pro, or Pixel 6a (as
a future addition). Such a DT will have certain nodes disabled / not
added. To facilitate such a generic gs101-based Pixel device, also add
a more generic gs101-pixel compatible. We can not just use the existing
google,gs101 for that, as it refers to the SoC, not a board.
