[U-Boot] [PATCH 00/16] pmic: Redesign PMIC framework to support multiple instances of devices

PMIC framework has been redesigned to support multiple instances of power related devices
(e.g. fuel gauge, PMICs, chargers, micro USB IC).

Due to that, code at other architectures and boards have been adjusted properly.

New power_board_init() method at ./lib/board.c file has been introduced. It is meant
to be an architecture dependent function to support advanced power management.
Since PMIC framework uses lists internally to link different devices, its initialization
must be done just after malloc initialization.

Please consider commits from this patch set as the example of advanced power management for a
particular HW (Trats board in this case).

In the new approach PMICs are selected with their names (e.g. 'pmic dump MAX8997_PMIC')
Presented patch set is a first step to change 'pmic' command to more generic (i.e. power)
to provide control for multiple devices.

Dependencies:
1. gpio:fix: Proper handling of GPIO subsystem parts at Samsung devices
http://patchwork.ozlabs.org/patch/181768/
2. i2c:soft:multi: Support for multiple soft I2C buses at Samsung boards
http://patchwork.ozlabs.org/patch/181789/
3. i2c:soft:multi: Enable soft I2C multibus at Trats development board
http://patchwork.ozlabs.org/patch/181788/

Test HW:
- Exynos4210 Trats development board
