atusb/fw: add EUI64 read and write fw interface to permanently set an EUI64

Browse Source 
The kernel driver will now ask for ATUSB_EUI64_READ during init and sets this
extended address if available. Use the atusb-eui64 utility from the tools folder
to read or set the permanent address.

After a new address is set the device will reset to make sure we are in a sane
state after the change.
