Markus Elfring 64dc362dee auxdisplay: ht16k33: Drop reference after LED registration 
[ Upstream commit 2ccfe94bc3 ]

The reference count is bumped by device_get_named_child_node()
and never dropped. Since LED APIs do not require it to be
bumped by the user, drop the reference after LED registration.

[andy: rewritten the commit message and amended the change]
