Since such format is deprecated in favor of the DT schema, let's convert the Generic xHCI Controllers bindings file to the corresponding yaml files. There will be two of them: a DT schema for the xHCI controllers on a generic platform and a DT schema validating a generic xHCI controllers properties. The later will be used to validate the xHCI controllers, which aside from some vendor-specific features support the basic xHCI functionality. An xHCI-compatible DT node shall support the standard USB HCD properties and custom ones like: usb2-lpm-disable, usb3-lpm-capable, quirk-broken-port-ped and imod-interval-ns. In addition if a generic xHCI controller is being validated against the DT schema it is also supposed to be equipped with mandatory compatible string, single registers range, single interrupts source, and is supposed to optionally contain up to two reference clocks for the controller core and CSRs.

Let's use the available DWC USB3 DT schema to validate the Qualcomm DWC3 sub-nodes. Note since the generic DWC USB3 DT node is supposed to be named as generic USB HCD ("^usb(@.*)?") one we have to accordingly fix the sub-nodes name regexp and fix the DT node example.
