usb: phy: qmp: Add support to select usb3 phy mode
qmp phy can run in display port mode or in usb3 mode. It is recommended to explicitly select the usb3 phy mode before programming the phy init sequence, since TCSR_USB3_DP_PHYMODE register is commonly used to select mode between display port driver as well as ssphy driver.
