[LEDE-DEV] Adding support for dlink dwr-512

[Giuseppe Lippolis]

Hi all,
I'm proceeding to finalize the support:
Now the wifi is enabled, the LEDs and the buttons are supported.

To complete the device support I need to:
	1. enable the 3G modem 
	2. crack the header file to generate the factory image

Will take some time.

In the meantime, here the patch:
