Subject: [PATCH 5/8] ARM: prima2: make use of of_find_matching_node_and_match

Instead of the of_find_matching_node()/of_match_node() pair, which requires two
iterations through the match table, make use of of_find_matching_node_and_match(),
which only iterates through the table once.

While we're here, mark the prima2_l2x0 table const.
