PCI: rcar-gen4: Fix -Wvoid-pointer-to-enum-cast error
When building with clang 18 with the -Werror compiler option enabled,
the following error will be reported:
drivers/pci/controller/dwc/pcie-rcar-gen4.c:439:15: error: cast to smaller integer type 'enum dw_pcie_device_mode' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
439 | rcar->mode = (enum dw_pcie_device_mode)of_device_get_match_data(&rcar->pdev->dev);
To fix this issue, cast the data the of_device_get_match_data() helper
returns to uintptr_t rather than the dw_pcie_device_mode enum.
