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.

Since the Pfuze initializations are similar on various mx6 SABRE
boards. Factorize the initialization to a common function in file
board/freescale/common/pfuze.c. So that all SABRE boards BSP can
share the function.
