Both of these are lpddr4 (It's assumed to be the default).
You need to name your board something else. v2 or w/e NXP calls it.
You may compare part numbers between old and new boards for
inspiration.

Moving the PMIC into the DTs should be separate commit. You can
move it into its own DTSI and include that optionally if you
want.

Moving common stuff into the imx8mm-evk.dtsi should be its own commit.
