The function imx_icc_unregister() returns zero unconditionally. Make it
return void.
This is a preparation for making platform remove callbacks return void.

icc_provider_del() already emits an error message on failure. In this
case letting .remove() return the corresponding error code results in
another error message and the device is removed anyhow. (See
platform_remove().)
So ignore the return value of icc_provider_del() and return 0
unconditionally.

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.

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

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.

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.
