juhosg 06add57343 ramips: rt305x: add support for the Asus WL-330N3G board
This patch adds support for the ASUS WL-330N3G

Comparing to the WL-330N, It have 32MB ram, usb support and a bicolor led.

The bi-color led is driven by 2 gpio.
I don't know how to handle this, so I simply made 2 leds : one red, one blue.
But the red light takes precedence over the blue one according to the chart below.

r = led is red
b = led is blue
0 = led is off

xy= x->r for red, b for blue led, y->value of brightness in /sys/class/leds/x/brughtness

initial state	action	 led	gpio state

r0	b0	r0->r1	 r  	r0	b0
r0	b0	b0->b1   b	r0	b1

r1	b0	r1->r0	 0	r0	b0
r1	b0	b0->b1	 r	r1	*b1*

r1	b1	r1->r0   b	r0	b1
r1	b1	b1->b0   r	r1	b0

r0	b1	r0->r1   r	r1	*b1*
r0	b1	b1->b0   0	r0	r0
