phy: qcom-qmp-usb: add support for updated qcm2290 / sm6115 binding 



Add support for the new qcm2290 / sm6115 binding.

The USB QMP phy on these devices supports 2 lanes. Note that the
binding now does not describe every register subregion and instead
the driver holds the corresponding offsets.

While at it also include support for PCS_MISC region which was left
out earlier.
