interconnect: imx: fix max_node_id 

[ Upstream commit bd734481e1 ]

max_node_id not equal to the ARRAY_SIZE of node array, need increase 1,
otherwise xlate will fail for the last entry. And rename max_node_id
to num_nodes to reflect the reality.

Fixes: f0d8048525 ("interconnect: Add imx core driver")
