powerpc/pmac: Fix DT refcount imbalance in pmac_pic_probe_oldstyle
Internally, of_find_node_by_name() calls of_node_put() on its "from"
parameter, which must not be done on "master", as it's still in use, and
will be released manually later. This may cause a zero kref refcount.
Call of_node_get() before to compensate for this.
