dt-bindings: phy: qcom,qusb2: do not define properties in "if" block

It is more readable to define properties in top-level "properties:" and
restrict them (if needed) per compatible in the "if" block.  Defining
properties in "if" block  does not work correctly with
additionalProperties:false:

  sc7180-trogdor-pazquel-lte-ti.dtb: phy@88e3000: 'qcom,bias-ctrl-value', 'qcom,charge-ctrl-value', 'qcom,hsdisc-trim-value',
    'qcom,imp-res-offset-value', 'qcom,preemphasis-level', 'qcom,preemphasis-width' do not match any of the regexes: 'pinctrl-[0-9]+'
