ieee802154: atusb: add support for trac feature

Browse source

This patch adds support for reading the trac register if atusb firmware
reports tx done. There is currently a feature to compare a sequence
number, if the payload is 1 it tells the driver only the sequence number
is available if it's two there is additional the trac status register as
payload.

Currently the atusb_in_good() function determines if it's a tx done or
rx done if according the payload length. This patch is doing the same
and assumes this behaviour.
