Revert "PCI: mvebu: Mark driver as BROKEN"

b3574f579e ("PCI: mvebu: Mark driver as BROKEN") made it impossible to
enable the pci-mvebu driver.  The driver does have known problems, but as
Russell and Uwe reported, it does work in some configurations, so removing
it broke some working setups.

Revert b3574f579e so pci-mvebu is available.
