Ok. I will make it generic in the next version. Thanks, Bhupesh

Add support for the new qcm2290 / sm6115 binding. The USB QMP phy on these devices supports 2 lanes. Also note that the binding now does not describe every register subregion and instead the driver holds the corresponding offsets. This also includes the PCS_MISC region.
