dt-bindings: PCI: brcm,stb-pcie: Add 7712 SoC description

Browse source

Add description for the 7712 SoC, a Broadcom STB sibling chip
of the Raspberry Pi 5.

The 7712 uses three reset controllers: rescal, for PHY reset
calibration; bridge, for the bridge between the PCIe bus and
the memory bus; and swinit, which is a "soft" initialization
of the PCIe HW.
