Nit: The device tree bindings mention two more properties as required
properties:
micbias-resistor-k-ohms
micbias-voltage-m-volts

However, both have "If this node is not mentioned", hence I guess they
are actually optional, but maybe we want to set an explicit value here?

I think it is a convention to move iomuxc at the very end for better
readability of the rest. At least the Vybrid dts and the more recently
added imx7d-sdb.dts follow this rule.

The 80 character limit normally is not enforced for device trees, hence
I would remove that line break here...

I do not have a strong opinion on comments, but if they are pure
duplication of what is already there, I kind of prefer to not add
them...

...and this seem not to be specified upstream? (at least not in
Documentation/devicetree/bindings/mmc/mmc.txt?)
Not sure about this... Or is label a common convention and hence
available for all nodes?

They are accessible on the i.MX6 SoC.. but maybe "on Apalis iMX6Q/D". Or
just remove the comment, since that is kind of what disabled says?
