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.

Looks good to me.

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.
