The U-Boot eMMC does not need to care about the power for Rockchip SoC, because if the board is using eMMC, the power will default on (for bootrom), and we do not do power management for it like kernel, so the 'vmmc', 'vqmmc' is only useful for SD in U-Boot.
This make U-Boot can boot into kernel even if the pmic driver is broken.
The rk3288-evb dts may be used in many boards using rockchip reference schematic but with little change, so we hope it can be more robust to boot into next stage.
