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.
