staging: comedi: ni_mio_common: implement INSN_CONFIG_GET_CMD_TIMING_CONSTRAINTS

Browse Source 
Adds implementation of the new INSN_CONFIG_GET_CMD_TIMING_CONSTRAINTS
instruction.  This patch also adds data for digital subdevices that are
streaming capable (within the ni_mio_* family).  Mostly, only the m-series
devices are capable of digital streaming.
