Subject: [PATCH v4 2/5] dt-bindings: arm: qcom: Mention that Chromebooks use a different scheme

The qcom.yaml bindings file has a whole description of what the
top-level compatible should look like for Qualcomm devices. It doesn't
match what Chromebooks do, so add a link to the Chromebook docs.

The link added here will (obviously) not function until the
documentation patch makes it to mainline. Presumably folks who want to
read it in the meantime can find it pretty easily. If there's a better
way to link this then please let me know.

Changes in v4:
- Use docs.kernel.org link.

Changes in v3:
- ("Mention that Chromebooks use a different scheme") split out for v3.
