alx: add a simple AR816x/AR817x device driver

Browse source 
This is a very simple driver, based on the original vendor
driver that Qualcomm/Atheros published/submitted previously,
but reworked to make the code saner. However, it also lost
a number of features (TSO/GSO, VLAN acceleration and multi-
queue support) in the process, as well as debugging support
features I didn't have any use for. The only thing I left
is checksum offload.

More features can obviously be added, but this seemed like
a good start for having a driver in mainline at all.

Johannes Stezenbach has verified that the driver works on
AR8161, I have a AR8171 myself. The E2200 device ID I found
on github in somebody's repository.

This driver supports the Qualcomm Atheros L1F ethernet adapter,
i.e. the following chipsets:
1969:1091 - AR8161 Gigabit Ethernet
1969:1090 - AR8162 Fast Ethernet
1969:10A1 - AR8171 Gigabit Ethernet
1969:10A0 - AR8172 Fast Ethernet
To compile this driver as a module, choose M here. The module
will be called alx.
