Whoops, thats a very good point. I hadn't twigged that
PCI_DRIVERS_LEGACY was MIPS specific (one of the disadvantages of using
"tig grep" I suppose!).

I think this is obviously correct, so it'd be great to squeeze it into
4.15 final.
Fortunately the other related change, commit 664eadd6f44b ("bcma: Fix
'allmodconfig' and BCMA builds on MIPS targets"), already depends on
MIPS so doesn't have the same issue.
Sorry for the breakage!
