Cc: Johannes Schneider
current(?) imx8mm EVKs come with a different PMIC: used to be
"rohm,bd71847", which is now replaced by "nxp,pca9450a" on the LPDDR4
variant at least the register settings etc where "backported" from
current u-boot sources for the EVK
Note: not sure if the changes should go in the ddr4-evk.dts or elsewhere;
what about backwards compatibility? = users/holders of the EVKs with the bd71847 IC?
changes with V4:
deduplicate rohm-pmic into one dtsi
changes with V3:
split changes into multiple commits
removed unused header
changes with V2:
reshuffle common nodes into the imx8mm-evk.dtsi, and only keeping the pmic related parts separate
