Devices are currently added at controller initialization time with 
boardinfo, but the i2c subsystem also supports dynamically adding 
devices through a variety of mechanisms including user-space through 
sysfs, device tree overlays and ACPI.

This small series decouples registration from the boardinfo and then 
adds a notifier to add the devices at runtime.  A future series will 
build on this to allow adding the I2C devices through ACPI.
