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 V11:
	correct (?) regulator min/max from:
	8MMINILPD4-CPU  SPF-31399_C2.pdf

changes with V10:
	- keep rhom-pic node untouched, for the "old" evks, and
	  delete+replace the node in the newer evks = EVKB
	- migrate voltage levels set for the rhom to the nxp pmic

changes with V9:
	drop 'rev b' references

changes with V8:
	rewording of commit messages, to reference "EVKB" instead of "rev-b"

changes with V7:
	add missing "acked-by" tag
	(finally) add missing makefile entry for imx8mm-evbk.dtb

changes with V6:
	move A53 cpu-supply nodes back into imx8mm-evk.dtsi
	rewording of commit messages
	fix syntax error during compile

changes with V5:
	split of bindings into separate commit
	rewording of commit messages

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
