In case we want to force a particular value on a regulator
irrespective of the min/max constraints for testing purposes
one can call regulator_set_value_force function.

Commit a85362fb3e1fc7833723accddbbae431091d06b8 refactored the code
but the register read ended up in the wrong if branch.
Currently, the else branch checks a variable which is always 0.

According to the binding documentation the fixed regulator enable GPIO
is optional. However so far registration thereof failed if no enable
GPIO was specified. Fix this by making it entirely optional whether an

When booting from USB, the bootrom sets the VUSB_IN_PMID bit of the MISC2
register of the TWL6030. However, U-Boot sets the VUSB_IN_VSYS bit to enable
VBUS input. As both bits are contradictory, enabling both disables the input,
according to the TWL6030 TRM.
Thus, we need to clear the VUSB_IN_PMID bit in case of an USB boot (which could
just as well be a memory boot after USB timed out).

This enables the VAUX1 supply, used for eMMC power in standard configurations.
Its voltage is determined by the value of the BOOT2 pin of the TWL6030.

SY8106A is a PMIC which is used on the Allwinner
H3 Orange Pi Pc and Plus board. The VOUT1_SEL register is
implemented to set the default V-CPU voltage to 1200 mV.
This driver is required to ensure the SY8106A V-CPU
voltage is set to 1200 mV after a software reset. On cold
boot the default SY8106A output voltage is selected to be
1200 mV by a pair of resistors on the Orange Pi PC and Plus.
