The TWL6030 power driver is only built when CONFIG_TWL6030_POWER is selected,
thus there is no reason to wrap the code with ifdef.
Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
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).

Not every device has multiple MMC slots available, so it makes sense to enable

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

implemented to set the default V-CPU voltage to 1200 mV.
This driver is required to ensure the SY8106A V-CPU
