interconnect: imx: fix max_node_id
[ Upstream commit bd734481e172b4827af09c9ab06c51d2ab7201e6 ]
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.

interconnect: imx: Simplify with dev_err_probe()
Common pattern of handling deferred probe can be simplified with
dev_err_probe(). Less code and the error value gets printed.

interconnect: imx: Fix return value check in imx_icc_node_init_qos()
In case of error, the function of_parse_phandle() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

interconnect: Add imx core driver
This adds support for i.MX SoC family to interconnect framework.
Platform drivers can describe the interconnect graph and several
adjustment knobs where icc node bandwidth is converted to a
DEV_PM_QOS_MIN_FREQUENCY request.
The interconnect provider is probed through the main NOC device and
other adjustable nodes on the same graph are found from a
fsl,scalable-nodes phandle array property.
