Drop the second newline-

This contains no info - you can drop or replace puts with debug().

Ok - I do not know if CONFIG_FSL_PMIC_BITLEN is really needed, but we
can leave it.

Probably this comes from your testing - you can drop it or use debug()

...and we have not always a max8998 !

Replace with debug()

You can leave away the MX boards (and we have to change all of them or
none of them - there are also MX3 boards that can use the new code).

Put changes to board configuration in a separate patch.
