Subject: [PATCH v2 1/8] dt-bindings: phy: qcom,qmp: Mark '#clock-cells' as a 'optional' property

Since '#clock-cells' is not a required property for qmp-phy(s)
(atleast in the '/' node, but is used in 'phy@' subnode),
so mark it as an optional property instead.

This fixes the following 'make dtbs_check' warning(s):

sm8350-microsoft-surface-duo2.dt.yaml: phy@...7000:
  '#clock-cells' is a required property

Also, make the dt-bindings confirm to changes
already made via commit 82d61e19fccb ("arm64: dts: qcom: msm8996:
 Move '#clock-cells' to QMP PHY child node"), by moving
'#clock-cells' property from the '/' node to the 'phy@' subnode.
