drivers: mfd: axp192: add possibility to disable N_VBUSEN functionality

Browse source 
By default N_VBUSEN signal is used by the host to define if VBUS
signal should be used for power supply (VBUS-IPSOUT).

This feature enables the possbibility to change this behaviour.
When N_VBUSEN detection is disabled, axp192 will automatically
decide to use VBUS (REG10H[7] = 1).
Please refer to datasheet for details.

This option will disable VBUS power control via N_VBUSEN.
By default VBUS power supply is chosen via N_VBUSEN pin.
When disabled, VBUS can by chosen automatically by the pmic
and there is no need by the host to control N_VBUSEN pin.
Please refer to datasheet for details (pin state (REG10H[7] = 1).
