Signed-off-by: Przemyslaw Marczak <p.marczak at samsung.com>
---
Changes v2:
- remove board_init_i2c() call
- update regulator calls
- update headers
- samsung/misc.c: include required header

Changes v3:
- adjust regulator calls to new api

Changes V4:
- use regulator_list_autoset() for mmc regulators
