dt-bindings: PCI: ti,j721e-pci-host: Add support for J722S SoC

Browse Source 
TI's J722S SoC has one instance of a Gen3 Single-Lane PCIe controller.
The controller on J722S SoC is similar to the one present on TI's AM64
SoC, with the difference being that the controller on AM64 SoC supports
up to Gen2 link speed while the one on J722S SoC supports Gen3 link speed.

Update the bindings with a new compatible for J722S SoC.
