Christian Lamparter f3ffac90bc ath79: gmac: add parsers for rxd(v)- and tx(d|en)-delay for AR9344 
Some AR9344 boards do very poorly with the default settings and
need custom rxdv-delay, rxd-delay, txd-delay, txen-delay flags
to perform reasonably.

In this case the WD My Net Wi-Fi Range Extender can not even
manage 10Mbps on a 1Gbit link:

root@AR9344:~# iperf3 -s
-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------
Accepted connection from client [...]
[  5] local [...] connected to client
[ ID] Interval           Transfer     Bitrate

[  5]   1.00-2.00   sec   895 KBytes  7.33 Mbits/sec
[  5]   2.00-3.00   sec   762 KBytes  6.25 Mbits/sec

[ ID] Interval           Transfer     Bitrate
[  5]   0.00-10.03  sec  9.00 MBytes  7.52 Mbits/sec

with but with the correct settings in place, it does much better:

root@AR9344:~# iperf3 -s
-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------
Accepted connection from client [...]
[  5] local [...] connected to client

[ ID] Interval           Transfer     Bitrate
[  5]   0.00-10.04  sec   237 MBytes   198 Mbits/sec

The tx data and enable delay bits definitions are taken from Atheros'
AR9344 Data Sheet Section "8.6.1 Ethernet Configuration (ETH_CFG)" on
page 153.
