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.

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.
