This patch converts lowlevel_init.S to lowlevel_init_c.c. Add PMIC MAX77686 voltage settings for SMDK5250.
Changes in V2:
- Added early serial support.
- Moved patch 2 containing power apis to patch 1 due to dependency
- moved lowlevel_init.S to arch/arm/cpu/armv7/exynos and
renamed as lowlevel.S
- Moved power mode #defines to power.h
- added error check for PMIC voltage settings.

Sorry for only chiming in at V2 stage, but... lowlevel_init is supposed to be the earliest code run ever, and is supposed to set up the environment for possibly, later, setting up a C environment. So what exactly sets up the C environment *for* lowlevel_init to be able to run in C?
Amicalement,
