dt-bindings: PCI: renesas,r9a08g045s33-pcie: Document RZ/G3E SoC

Browse source

Extend the existing device tree bindings for Renesas RZ/G3S PCIe
controller to include support for the RZ/G3E (renesas,r9a09g047e57-pcie)
PCIe controller. The RZ/G3E PCIe controller is similar to RZ/G3S but has
some key differences:

 - Uses a different device ID
 - Supports PCIe Gen3 (8.0 GT/s) link speeds
 - Uses a different clock naming (clkpmu vs clkl1pm)
 - Has a different set of interrupts, interrupt ordering, and reset
   signals

Add device tree bindings for renesas,r9a09g047e57-pcie compatible IPs.
