From: Peng Fan <peng.fan@nxp.com>

Add i.MX8MP NoC node to make the interconnect i.MX8MP driver could work.
Currently dynamic frequency scaling of the i.MX8MP NoC has not been
supported, only NoC initial settings are configured by interconnect
driver.

Signed-off-by: Peng Fan <peng.fan@nxp.com>

V4:
 Georgi has merged the V3 driver and bindings patches. So only resend
 this patch. Per Georgi's comments:
  - Drop syscon from compatbile
  - Drop the header inclusion

 Seems I not see this patch in patchwork or mailist, maybe sent failed.
 So gave a resend of V4.

 V3:
  https://lore.kernel.org/linux-arm-kernel/20220703091132.1412063-1-peng.fan@oss.nxp.com/

 I not list the full change log, since this is only a minor patch
