Instead of fwnode_get_named_gpiod() that I plan to hide away, let's use
the new fwnode_gpiod_get_index() that mimics gpiod_get_index(), bit
works with arbitrary firmware node.

Hi Dmitry,

(CC'ing Heikki as the original author of software nodes support)

Thank you for the patch.

On a side note, as I'm not very familiar with software nodes, I tried to
see how they are to be used, and it seems they are completely
undocumented :-( Heikki, is this something that could be fixed ?

OK. I'll start writing API documentation for it.
