  1. i2c: mux: Add support for generic base-nr property 

    i2c_mux_add_adapter takes a force_nr parameter that allows an explicit
bus number to be associated with a channel. However, only i2c-mux-reg
and i2c-mux-gpio make use of it.

To help with situations where it is desirable to have a fixed, known
base address for the channels of a mux, create a "base-nr" property.
When force_nr is 0 and base-nr is set and non-zero, form a force_nr
value from the sum of base-nr and the channel ID.

  2. overlays: i2c-mux: Add 'base' parameter 

    Add a 'base' parameter to set an explicit bus number for the channels,
where the requested bus number is base + channel ID.
