dt-bindings: phy: qcom,usb-snps-femto-v2: use fallback compatibles

Document SoC-specific compatibles with generic fallback (e.g.
qcom,usb-snps-hs-7nm-phy) already used in DTSI.  Add SoC-specific
compatibles for PHY on SDX55 and SDX65.

This disallows usage of the qcom,usb-snps-hs-5nm-phy and
qcom,usb-snps-hs-7nm-phy generic compatibles alone.  Do not touch
remaining two compatibles - qcom,usb-snps-femto-v2-phy and
qcom,sc8180x-usb-hs-phy - because there are no upstream users, so not
sure what was the intention for them.

This fixes warnings like:

  sa8295p-adp.dtb: phy@88e5000: compatible: 'oneOf' conditional failed, one must be fixed:
    ['qcom,sc8280xp-usb-hs-phy', 'qcom,usb-snps-hs-5nm-phy'] is too long
    'qcom,sc8280xp-usb-hs-phy' is not one of ['qcom,sm8150-usb-hs-phy', 'qcom,sm8250-usb-hs-phy', 'qcom,sm8350-usb-hs-phy', 'qcom,sm8450-usb-hs-phy']
    'qcom,usb-snps-hs-7nm-phy' was expected
