[PATCH, RESEND] arm: kirkwood: readynas duo v2: Add GMT G762 Fan Controller

[Arnaud Ebalard]

Now that GMT G762 PWM Fan Controller is available upstream, let's add
missing bindings in Netgear ReadyNAS Duo v2 .dts file.

Hi Jason and Andrew,

This one applies and has been tested against Stephen Rothwell tree.
Can you make it flow to Linus tree during the merge window?

Following Thomas feedback, this is a resend of previous version, this
time w/o fixes for bad spaces at the end of the file. Just tell me if
I should send a separate one for that purpose.

Thanks in advance.

Cheers,

a+
