bsp/atsam: Remove side effect from gmac functions.

Quite a number of GMAC_... functions had a side effect of enabling the
transmit and receive. During the initialization of the ethernet driver,
that lead to the situation that the receive has been already enabled
while the DMA isn't set up correctly. Therefore the DMA interpreted the
values at address 0 as an DMA descriptor. When a packet is received
during that time, the behaviour is quite undefined.
