This patchset adds the support for USB SS qmp phy for Qualcomm SM6115
SoC. For the previous versions of this patch there were conversations
on irc as to whether this was a 'qcom,usb-ssphy-qmp-usb3-or-dp' or a
'qcom,usb-ssphy-qmp-dp-combo' as per downstream code and hardware
documentation.

But after a careful look at downstream dtsi (see [1]) it appears that
this indeed is a 'qcom,usb-ssphy-qmp-usb3-or-dp' phy and not a
'dp-combo' phy.
