This adds the Alacritech slicoss driver to the tree.

This driver is supposed to support:

Mojave cards (single port PCI Gigabit) both copper and fiber
Oasis cards (single and dual port PCI-x Gigabit) copper and fiber
Kalahari cards (dual and quad port PCI-e Gigabit) copper and fiber

The driver was acutally tested on Oasis and Kalahari cards.

TODO:
- move firmware loading to request_firmware()
- remove direct memory access of structures
- any remaining sparse and checkpatch.pl warnings
- any netdev recommended changes

Many thanks to Lior Dotan for help with the cleanup
of this driver.
