f6acabcbdc ar71xx: enable ethernet LED of Arduino Yun
Commit 05d73a2a73 enabled GPIO on ethernet LED, but proper LED setup was
not added then. This commit fixes it by reverting the change on the LED.

f3c0eab9c7 Revert "ar71xx: fix Arduino Yun enabling of level shifters outputs"
This reverts commit 077253dd66.

The output enable pins should be disabled by default, and only enabled when
used. Otherwise unwanted conflicts might occur between MCU and SoC pins.

077253dd66 ar71xx: fix Arduino Yun enabling of level shifters outputs
As show in Arduino Yun schematic [1] GPIO 21 and 22 are connected to
output enable pin (OE) of two NTB01xx level shifters.

NTB01xx datasheets [2] [3] states that OE pin are active-high
therefore we should initialize GPIO 21 (DS_GPIO_OE) and GPIO 22
(DS_GPIO_OE2) accordingly to actually enable level shifters outputs.

fa137d51f5 ar71xx: add Arduino Yun
This is based on patches from Federico Fissore <f.fissore@arduino.cc>
especially this one:
7e2976fa83

The console is running with 250000 baud which is a non standard baud
rate and needs an extra patch to be applied, I will try to get this
patch upstream or something else which accomplish the same.

Some upstream code looks like there are many different versions of this
SoC, are these only internal versions and all versions on the consumer
market are the same? I saw different GPIO configuration and flash sizes
of 8MB and 16MB?
