[PATCH] arm: kirkwood: readynas duo v2: Add GMT G762 Fan Controller DT bindings

[arno@natisbad.org (Arnaud Ebalard)]

Now that GMT G762 PWM Fan Controller is available upstream, let's add
missing bindings in Netgear ReadyNAS Duo v2 .dts file. Let's also take
the opportunity to fix space issues at the end of the 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? Thanks
in advance.

Cheers,
