[PATCH V3 10/10] arm64: dts: imx8mp: add NoC node

From: Peng Fan <peng.fan at 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.
