Add support for "driverinit" configuration mode value for devlink_port
configuration parameters. Add devlink_port_param_driverinit_value_get()
function to help the driver get the value from devlink_port.
Also, move the common code to __devlink_param_driverinit_value_get()
to be used by both device and port params.
