[PATCH v2 1/5] dt-bindings: arm: google: Add dt bindings for frankel/blazer/mustang

[Peter Griffin <peter.griffin@linaro.org>]

Add binding documentation for Tensor G5 SoC (Laguna) which is referred
to in code as "lga" and three of the boards that use the Laguna SoC
Frankel (Pixel 10), Blazer (Pixel 10 Pro) and Mustang (Pixel 10 Pro XL).

Additionally update to use a more efficient and scalable way to express
the various names a SoC is known by.

Changes in v2:
 * Update ect rule as per Krysztof suggestion
 * Remove all the pre-production variants (EVT, DVT etc)
 * The equivalent patch in the previous submission is
   https://lore.kernel.org/lkml/05c833f0-15bc-4a86-9ac4-daf835fe4393@kernel.org/
   but this is now almost entirely different diff. I've added the
   co-developed-by tag as I've kept the more efficient way to express
   the names a SoC is known by.

-  Google have a few different names for the SoC:
-  - Marketing name ("Tensor")
-  - Codename ("Whitechapel")
-  - SoC ID ("gs101")

-  Likewise there are a couple of names for the actual device
-  - Marketing name ("Pixel 6")
-  - Codename ("Oriole")

-  Devicetrees should use the lowercased SoC ID and lowercased board codename,
-  e.g. gs101 and gs101-oriole.
