dt-bindings: arm: qcom: drop the superfluous device compatibility schema

The idea impressed in the commit b32e592d ("devicetree: bindings:
Document qcom board compatible format") never got actually adopted. As
can be seen from the existing board DT files, no device actually used
the PMIC / foundry / version parts of the compatible string. Drop this
compatibility string description to avoid possible confusion and keep
just the generic terms and the SoC list.

-  Each board must specify a top-level board compatible string with the following

-  The 'SoC' and 'board' elements are required. All other elements are optional.
