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.
