Later QMP USB PHY blocks 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). In preparation for adding new bindings for SC8280XP which further bindings can be based on, rename the current bindings after MSM8996 and add a reference to the SC8280XP bindings.
