The 'regulator-mode' of this patch means following defined constant variable
as following in include/linux/regulator/consumer.h:
#define REGULATOR_MODE_FAST 0x1
#define REGULATOR_MODE_NORMAL 0x2
#define REGULATOR_MODE_IDLE 0x4
#define REGULATOR_MODE_STANDBY 0x8
If regulator consumer would use this mode('regulator-mode),
specific regulator driver should implement rdev->desc->ops->set_suspend_mode function
to control regulator state according to 'regulator-mode' in suspend state.
