commit dd66cc2e1 "drm/pci: Use PCI Express Capability accessors" introduced the use of the pcie_capability_read_dword function in the drm_pci code, which is only defined when PCI is enabled. While most of the file is already hidden away behind an #ifdef CONFIG_PCI, this function is not, and that now causes a link error in the ARM imx_v6_v7_defconfig configuration. Moving the function into the #ifdef section makes this work again on IMX, which does not have PCI support, and should have no impact on platforms that do.
