The QMP USB PHY block only provide a single PHY and the remnant child node does not really reflect the hardware. The original MSM8996 binding also ended up describing the individual register blocks as belonging to either the wrapper node or the PHY child nodes. This is an unnecessary level of detail which has lead to problems when later IP blocks using different register layouts have been forced to fit the original mould rather than updating the binding. The bindings are arguable also incomplete as they only the describe register blocks used by the current Linux drivers (e.g. does not include the per lane PCS registers). Note that PCS_USB region is also not described by the current bindings despite being used by the driver and this has led to people increasing the size of the PCS region in the devicetree so that it includes PCS_USB registers even though other regions like TX and RX may lie in between. Add a new binding for the QMP USB PHYs found on SC8280XP which further bindings can be based on. Note that this also fixes the SC8280XP "phy_phy" reset name. Also note that the current binding is simply removed instead of being deprecated as it was only recently merged and support for SC8280XP is still under development. And, specifically, there is no support in mainline for the multiport controller that uses these PHYs.
