wifi/pc: add ath9k driver

Browse Source 
The driver was only tested with an "Atheros AR9462 Rev:2" [168c:0034]
device using the 'wifi.run' run script.

Note: for it to work MSI may not be used as otherwise interrupts do not
work. Using an IOMMU leads to the following fault:

[ 0] IOMMU:0xffffffff817eb0b0 FRR:0 FR:0x22 BDF:4:0:0 FI:0xb0000000000000 (0)
