regulator: tps65086: Select dedicated regulator config for chip variant

Some configurations differ between chip variants, e,g. the register
to control the on of state of LDOA1 and SWB2. Thus, it is necessary
to choose the correct configuration for a dedicated device.
If the wrong configuration was used, the LDOA1 output that was
disabled by the bootloader was enabled in  Kernel again.

Each chip variant gets its dedicated configuration selected by
the chip ID previously collected from MFD probe function.
The VTT enum value (tps65086_regulators) is shifted because not all
chip variants have a separate SWB2 switch. Sometimes they are merged.
So the configuration possibilities differ, thus the regulator
configuration arrays have a different length.
