Sync dts for imx8mn-evk with Linux Kernel and change name for PMIC used in SPL.

commit 1cfa1e68af8d40ab233d5d27bc8446e4c5107571("arm64: dts: imx8mn-evk: fix the min/max voltages of the PMIC")
commit bc046b952a5494b0dc53be28779460cee1214a3f("arm64: dts: imx8mn-evk: use proper names for PMIC outputs")
