I have PCI=n, hence BRCMFMAC_PCIE=n.

IIRC, I did try adding the HAS_DMA dependencies to the suboptions,
but then it still failed to link. Hence I restored to the main BRCMFMAC.

Besides, msgbuf.o is part of the core.
I've just tried moving it to brcmfmac-$(CONFIG_BRCMFMAC_PCIE),
but that doesn't help. Other parts use msgbuf, too.
