i.MX8MP has a design that NoC(Not main NoC) is distributed in multiple
blocks, such as vpumix, hsiomix and etc. The access to NoC requires
power domain on and blk ctrl settings configured.

So the design here is for mixes that not have blk-ctrl, configure
the NoC in gpcv2 driver, for mixes that have blk-ctrl, configure
the NoC in blk-ctrl drivers.

This v1 patchset not apply on Shawn's tree, I picked up Lucas's HSIO
and Laurent's mediablk patches, then worked out this patchset:

Note: This interconnect related functions not added. This patchset
is only to replace the function did in NXP downstream:
