[RFCv4,6/7] soc: imx8mm: Register interconnect platform device

Commit Message

Leonard Crestez Aug. 23, 2019, 2:36 p.m. UTC

Since there is no virtual devicetree node representing the interconnect
we need to probe the icc device externally. Probing this from the SOC
driver allows the interconnect device to be built as a module.

This is very similar to imx-cpufreq-dt.
