ar71xx: TL-MR3020: fix board detection, fix missing mandatory package and modify LED behaviour

This patch fixes the board detection of the TL-MR3020.

The LED behaviour has also been modified:
* The WPS LED is the diag LED now.
* A netdev trigger for the LAN LED has been added.

The profile of the TL-MR3020 has been updated because the needed package
"kmod-ledtrig-usbdev" was missing which resulted in a non-working usbdev
trigger for the 3G/USB LED.

[juhosg: the board name changes has been removed, and the kernel files
has been changed instead.]
