ALSA: aoa: i2sbus: fix OF node lifetime handling
i2sbus_add_dev() keeps the matched "sound" child pointer after
for_each_child_of_node() has dropped the iterator reference. Take an
extra reference before saving that node and drop it after the
layout-id/device-id lookup is complete.
The function also stores np in dev->sound.ofdev.dev.of_node without
taking a reference for the embedded soundbus device. Since i2sbus
overrides the embedded platform device release callback, balance that
reference explicitly in the local error path and in i2sbus_release_dev().
