The i.MX8M Mini has supports the MICFIL digital interface.
It's a 16-bit audio signal from a PDM microphone bitstream.
The driver is already in the kernel, but the node is missing.
This patch adds the micfil node.

The i.MX8M Mini can support SPDIF which is compatible to the
IP used on the i.MX35. Add the node.

The i.MX8M Mini has micfil and SPDIF support but the drivers
are not being loaded.
This patch updates the defconfig to add support for these drivers.
