Enabling the PCI_MVEBU driver for compile testing caused a build failure
on ARM randconfig builds:

The problem is that the mbus helper functions are not declared in the
header. There are two ways of solving this: we can change the header
to provide empty stub functions for CONFIG_MVEBU_MBUS=n, or we can
add back the dependency here.
I picked the second option since that is simpler, but it somewhat
defeats the purpose of the original patch because we still cannot
compile test on other platforms this way.

Probably better to just make these non-standard dependencies explicit.

Thanks, I added this when doing the merge.
