dt-bindings: PCI: Add ZTE ZX279128S host controller
This commit adds the Device Tree binding for the DesignWare PCIe host
controller on the ZTE ZX279128S SoC. It defines the required registers,
interrupts, clocks, resets, and PHYs. It also introduces optional board-level
GPIOs for resets and enable lines.

[Severity: Low]
Does this custom enable-gpios property bypass the regulator framework?
In Device Tree, board power or enable lines should typically be modeled using
standard regulator bindings (such as vpcie-supply) linked to a regulator-fixed
node, rather than using hardcoded raw GPIO properties directly in the PCIe
controller node.
A review of existing PCI bindings shows no other uses of enable-gpios. Could
this be modeled with a standard regulator instead?
