overlays: Factor out the common i2c bus selection

Browse Source 
Create an i2c-buses.dtsi to hold all of the common I2C bus selection
logic, and refactor existing overlays to use it. This patch should
have no functional change overall except to increase the range of
options for some overlays.

There is a slightly ugly mechanism for overriding the default bus, where
the mux nodes may or may not need to be enabled.
