28a3a43d7b power: twl6030: fix code refactoring
Commit a85362fb3e 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.

6313c65004 power: twl6030: Clear VUSB_IN_PMID bit on USB device setup
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 driver is required to ensure the SY8106A V-CPU

boot the default SY8106A output voltage is selected to be
1200 mV by a pair of resistors on the Orange Pi PC and Plus.
