net: asix: add write_hwaddr function

Browse source 
All ASIX chipsets aside from AX88172 are able to set the MAC
address on the hardware level. Add a function to expose this
ability.

To differentiate between chip types we now carry flags as driver
private data. Also while touching the asix_dongles array
constify this.
