ar71xx: fix 100/10mbps ethernet link issues on mynet range extender

The mynet range extender hardware is suffering from ethernet
link loss when booting with a recent openwrt image. This only
happens on 100mbps links, with 1Gbps speed the link was fine.

The cause of the problem is that the AR8035 PHY (aka F1E)
requires turning on and off the special TX delay setting
depending on the speed of the link.

The 10mbps mode only needed the proper pll value, which was
extracted from the vendor code.

ar71xx: improve WD's My Net Wi-fi Range Extender image creation

Previously, the generated images for the My Net Wi-fi Range Extender
wouldn't always work (and panic) due to the fixed mtd offsets and
sizes for the kernel and rootfs. This patch fixes the problem by
utilizing the shared Cybertan's partition parser to recalculate
the mtd partitions for every image dynamically everytime.

ar71xx: improve support for the My Net Wi-Fi Range Extender device

This patch improves support for the device considerably.

1. The wifi didn't work in the initial release. This was because
the WMAC of the AR9340 is not connected to the antennas.
(However, it can pick up wifi signals, if they are strong enough!)
Instead there's a dedicated AR9300 chip on the same board, which
works.

2. Ethernet throughput is improved. iperf shows that the hardware
can sustain more than 200Mbit/s and no longer drops any packages
when the link is under load.

ar71xx: add kernel support for the My Net Wi-Fi Range Extender device

This patch adds a new device definition for a
Western Digital device. The hardware seems to
be based on Qualcomm Atheros DB120 design.
