This driver only a cmd->start_src of TRIG_NOW or TRIG_INT. The cmd->start_arg
is trivially validated for both sources to be 0. For a TRIG_INT source, the
cmd->start_arg is actually the valid trig_num that is passed to the async
(*inttrig) callback.
Refactor the (*inttrig) function so that the cmd->start_arg is used to check
the trig_num instead of the open coded value.
