[PATCH v3 1/3] dt-bindings: clock: qcom: glymur-gcc: Add missing CX power domain

[Abel Vesa]

The GDSCs provided by the Glymur GCC are supplied by the RPMh CX power
domain. Model that parent domain in the GCC binding so the provider can
describe the dependency in devicetree.

Add a single CX power-domain entry to the binding and make it required,
matching the hardware description needed by the GCC node.
