dt-bindings: clock: qcom: Move glymur TCSR to own binding

The QREF block supplies reference clocks to PCIe PHYs and requires
dedicated LDO supplies to operate. The digital control interface for QREF
(clkref_en registers) resides in TCSR on glymur. Since QREF has no
dedicated DT node of its own, these supply properties are placed in the
TCSR node which acts as the control interface for QREF.

Add a dedicated binding file for qcom,glymur-tcsr and document the supply
properties. As this binding will grow to cover more SoCs, mark the
required supplies per compatible using an allOf/if/then conditional.
