This small series of two patches enable (PCI) DMA support in MCB.
The first patch enables PCI bus mastering by default for all
PCI-based MCB devices.
The second patch adds a dma_device to the mcb_device for all devices
as a shortcut to mcb_device->bus->carrier.
Michael Moese (2):
Enable PCI bus mastering by default
Add a dma_device to mcb_device

I'm sorry for the errors in the patches.
I'll correct them and resend everything.
