Edoardo Scaglia 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.
