When building with clang 18 I see the following warning:
|       drivers/pci/controller/pcie-iproc-platform.c:55:15: warning: cast to smaller
|                integer type 'enum iproc_pcie_type' from 'const void *' [-Wvoid-pointer-to-enum-cast]
|          55 |         pcie->type = (enum iproc_pcie_type) of_device_get_match_data(dev);

To fix this issue, use uintptr_t instead.
