I sent Dave the patch below last Friday. It's essentially the same
as yours, Fabio.
commit ed0708e69f71fab656afc1c891f3c54c9b105664

drm/pci: define drm_pcie_get_speed_cap_mask() only when CONFIG_PCI=y
Move drm_pcie_get_speed_cap_mask() under #ifdef CONFIG_PCI because it
it used only for PCI devices (evergreen, r600, r770), and it uses
PCI interfaces that only exist when CONFIG_PCI=y.
Previously, we tried to compile drm_pcie_get_speed_cap_mask() even when
CONFIG_PCI=n, which fails.
