Add support for the Qualcomm QMP USB3-DP Combo PHY found on
SC7280 and QCM6490 platforms. This driver currently implements
USB3 super-speed functionality of the combo PHY.
The QMP Combo PHY is a dual-mode PHY
that can operate in either USB3 mode or DisplayPort mode. This
initial implementation focuses on USB3 mode to enable Super-Speed
USB support.
Taken from Linux commit 3d25d46a255a ("pmdomain: qcom: rpmhpd: Add rpmhpd support for SM8750")
