PCI: rzg3s-host: Add support for RZ/V2H(P) SoC
Add support for the RZ/V2H(P) SoC PCIe controllers to the rzg3s-host
driver.
The RZ/V2H(P) SoC features two independent PCIe controllers that share
four physical lanes. The hardware supports two configuration modes:
single x4 mode where the first controller uses all four lanes, or dual
x2 mode where both controllers use two lanes each.
Introduce a setup_lanes() function pointer to configure the PCIe lanes
based on the hardware instance. Implement rzv2h_pcie_setup_lanes() to
detect the configuration at boot time and program the lane mode via the
system controller.
