[U-Boot] [PATCH 12/12] ARM:imx call ldo_mode_set in arch_preboot_os

[Peng Fan]

Current i.MX6 U-Boot does not support device tree. We check
ldo-bypass from dtb file which is loaded when running
`run loadfdt`.

Future work is needed to integrate device tree in uboot. And move
related function invoke in power_init_board.
