Allocate an explicit i2c mux core to handle parent and child adapters etc. Update the select/deselect ops to be in terms of the i2c mux core instead of the child adapter. Add a mask to handle the case where not all child adapters should cause a mux deselect to happen, now that there is a common deselect op for all child adapters.
