Subject: [PATCH v6 03/13] dt-bindings: PCI: brcmstb: Add 7712 SoC description
Add description for the 7712 SoC, a Broadcom STB sibling chip of the RPi 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.
