phy: qualcomm: qmp-usb: Add support for Glymur USB UNI PHY 



Glymur contains a USB multiport controller which supports a QMP UNI PHY.
These ports do not have typeC capability, so it needs to be differentiated
in this manner.  Update the QMP PHY sequence required to bring up the UNI
PHY for Glymur.  The UNI PHY follows mostly the same register field
definitions as previous SoCs.
