    lantiq: fix pcie driver build warnings
    
    This patch fixes the following build warnings:
    
    arch/mips/pci/ifxmips_pcie.c:1084:36: error: invalid use of undefined type 'struct platform_device'
     1084 |     struct device_node *node = pdev->dev.of_node;
          |                                    ^~
    arch/mips/pci/ifxmips_pcie.c:1204:12: error: no previous prototype for 'ifx_pcie_bios_init' [-Werror=missing-prototypes]
     1204 | int __init ifx_pcie_bios_init(void)
          |            ^~~~~~~~~~~~~~~~~~
