First stubs for a new driver for the Marvell Libertas chips.

The card correctly loads the firmware and it is possible to send a few
simple commands to the card but that's it. No packet are sent or received.
Only the Netgear WG511v2 cardbus card is tested.
A cheese fondue and a bigger amount of white wine was needed to make the
interrupts work -- until last night the driver was uploading the firmware
to fast and the card garbled the image without moaning. It took us a full
day and hundreds of test kernels to figure that out.
Joint work with mglocker@, fondue by mbalmer@
OK mglocker@, get it in deraadt@
