devlink: Add devlink_param register and unregister

Define configuration parameters data structure. Add functions to register and unregister the driver supported configuration parameters table. For each parameter registered, the driver should fill all the parameter's fields. In case the only supported configuration mode is "driverinit" the parameter's get()/set() functions are not required and should be set to NULL, for any other configuration mode, these functions are required and should be set by the driver.
