i2c: mux: mlxcpld: Add callback to notify mux creation completion
Add notification to inform caller that mux objects array has been
created. It allows to user, invoked platform device registration for
"i2c-mux-mlxcpld" driver, to be notified that mux infrastructure is
available, and thus some devices could be connected to this
infrastructure.
