The change in i2c configuration added to support access to the VPD has inadvertantly caused access to i2c buses 1 & 2 to be lost. This has resulted in the configuration for the PMIC to be attempted on the wrong bus and thus isn't taking effect.
Add the required configuration to return access to buses 1 & 2. In order to ensure that any users of the bus numbering prior to addition in VPD patches work, add buses before configuration related to mux on bus 0 and tweak VPD bus usage to fit new numbering scheme.
