MLK-23844-1: ARM64: dts: freescale: imx8mn-ddr4-evk: cleanup Rhom pmic
Inculding below cleanup for BD71847 pmic driver:
--Remove ldo4 which's not used by board, otherwise,ldo4 will be on
since it's always_on.
--Remove buck5 which's not used by board too,although that may be off
by kernel requlator common framework after kernel bootup.
--Add dvs-run-voltage/dvs-idle-voltage setting for buck2 as i.mx8mm.
