pmic:pfuze implement pmic_mode_init
This patch is to implement pmic_mode_init function, and add prototype
in header file.
This function is to set switching mode for pmic buck regulators to
improve system efficiency.
Mode:
OFF: The regulator is switched off and the output voltage is discharged.
PFM: In this mode, the regulator is always in PFM mode, which
is useful at light loads for optimized efficiency.
PWM: In this mode, the regulator is always in PWM mode operation
regardless of load conditions.
APS: In this mode, the regulator moves automatically between
pulse skipping mode and PWM mode depending on load conditions.
