ipq806x: replace linux,part-probe with a proper partitions subnode

Browse source 
This solution is more upstream compatible as it only requires specifying
of_match_table in the parser code and doesn't depend on linux,part-probe
which is solution made generic by a LEDE downstream patch that can't be
upstreamed.
