[PATCH v4] dt-bindings: phy: Add QMP UFS PHY compatible for QCS8300

[Jingyi Wang]

From: Xin Liu <quic_liuxin at quicinc.com>

Document the QMP UFS PHY compatible for Qualcomm QCS8300 to support
physical layer functionality for UFS found on the SoC. Use fallback to
indicate the compatibility of the QMP UFS PHY on the QCS8300 with that
on the SA8775P.
