This patchset is to support i.MX8MP NoC settings, i.MX8MP NoC initial
value after power up is invalid, need set a valid value after related
power domain up.
This patchset also includes two patch[1,2] during my development to enable
the ICC feature for i.MX8MP.
I not include ddrc DVFS in this patchset, ths patchset is only to
support NoC value mode/priority/ext_control being set to a valid value
that suggested by i.MX Chip Design Team. The value is same as NXP
downstream one inside Arm Trusted Firmware:

Add bindings for Qualcomm SM6350 Network-On-Chip interconnect devices.
As SM6350 has two pairs of NoCs sharing the same reg, allow this in the
binding documentation, as was done for qcm2290.

The QUP0 BCM relates to some internal property of the QUPs, and should

The QUP ports exist in the topology, but are not exposed as an
endpoints in DT. Fix this by creating IDs and attach them to their
NoCs, so that the various QUP drivers (i2c/spi/uart etc.) are able
to request their interconnect paths and scale their bandwidth.
