usb: phy-msm-ssusb-qmp: Update portselect when in USB+DP mode

Currently the driver is writing to USB3_PHY_PCS_MISC_TYPEC_CTRL
register for portselect but in case of USB_DP mode this register
will not be present. This can lead to invalid register access.
Fix this by writing portselect to USB3_DP_COM_TYPEC_CTRL register
in USB+DP mode.
