The i.MX8MP has a micfil controller which is used for interfacing with a pulse density microphone. Add the node and mark it as disabled by default.

Nak. I guess I'll Nak myself.

After a bunch of attempts to get this working on real hardware, it turns out that IMX8MP_CLK_AUDIOMIX_PDM_ROOT doesn't really exist. Its real name is IMX8MP_CLK_AUDIOMIX_PDM_SEL. I'll submit a patch to remove this from imx8mp-clock.h and and a V3 of this series to update the clock reference in this node.
