MLK-23275-3: regulator: bd71837: correct ldo1/ldo2 group
Only one group voltage support on L4.14 so that the below two patches for
dts are not enough since 1.8V/0.8V not support by pmic driver:
commit 1c923bdd27021b011358f9422a6a18cbf30de491
("MLK-23275-2: ARM64: dts: freescale: fsl-imx8mn-ddr4-evk: correct ldo1/ldo2 voltage")
commit 8574922dd583141a332be58fe1656ee05c9e5dd4
("MLK-23275-1: ARM64: dts: freescale: fsl-imx8mm-evk: correct ldo1/ldo2 voltage")
So change ldo1/ldo2 voltage to 1.6V~1.9V/0.8V per i.mx8mm/i.mx8mn for quick
fix. For the kernel from L4.19, no need this patch.
