field 'pci_controller' has incomplete type
Bisect points to commit d41e6858ba58c ("MIPS: Kconfig: Set default MIPS
system type as generic") as the culprit. Analysis shows that the commmit
changes PCI configuration and enables PCI_DRIVERS_GENERIC. This in turn
disables PCI_DRIVERS_LEGACY. 'struct pci_controller' is, however, only
defined if PCI_DRIVERS_LEGACY is enabled.
Ultimately that means that BCMA_DRIVER_PCI_HOSTMODE depends on
PCI_DRIVERS_LEGACY. Add the missing dependency.

I am aware that this problem has been reported several times. I have
not been able to find a fix, but I may have missed it. If so, my
apologies for the noise.
I should have said "I have not been able to find a patch fixing it".
Also note that this is not the only fix required; commit d41e6858ba58c,
as simple as it looks like, does a pretty good job messing up
"mips:allmodconfig" builds.
... nor did I find patch(es) fixing the other build problem(s) introduced
by d41e6858ba58c.
