net/macb: add TX multiqueue support for gem
by: Cyrille Pitchen
1. macb driver will check the register to find how many queues support for
this chip.
2. Then as we only use queue0 for tx, so we will set up all other queues
use a dummy descriptor, which USED bit is set. So those queues are not used.

Driver for the Atmel MACB on-chip ethernet controller.
This driver has been tested on the ATSTK1000 board with a AT32AP7000
CPU. It should probably work on AT91SAM926x as well with some minor
modifications.
Hardware documentation can be found in the AT32AP7000 data sheet,
which can be downloaded from
