LF-3811 net: fec: fix TX Bandwidth Fluctuations

MAC-NET IP with AVB support, queue 0 for best-effor, and queue 1&2 for AVB.
The default bandwidth configured of queue 1&2 is 50% in the driver, which
leads to TX bandwidth fluctuations when selecting queue 1&2 for transmitting
packets. Select queue based on VLAN info when AVB enabled.

Commit da722186f654 ("net: fec: set GPR bit on suspend by DT configuration.")
refactor the fec_devtype, need adjust downstream code accordingly.
