Fix child-node lookup during probe, which ended up searching the whole

To make things worse, the parent mfd node was also prematurely freed.
Note that the nodes returned from the two calls to of_parse_phandle()
are also leaking, but fixing that is a bit more involved as pointers to
node fields are being stored for later use.
Is using a devm_kstrdup() to remember the full_name sufficient so get
each of the FIXMEs cleaned up as well?
Yeah, that may be sufficient, but looking closer at this now, it seems
the name pointers (su1_fb and su2_fb) are only used as booleans, and the
fb_name pointer in struct as3711_bl_data is never used at all.
So cleaning that up somehow (e.g. and maybe even dropping non-dt
probing) would also work.
But since this is a separate, and less critical issue, I think it needs
to be done as a follow up to this one.
To be honest it was adding the separate and less critical FIXMEs into
the patches that attracted my attention in the first place. ;-)
Daniel.
