staging: comedi: ke_counter: add ability to select counter clock source

Browse source

Add an (*insn_config) to the counter subdevice to allow the user to select
the clock source for the counters using the INSN_CONFIG_SET_CLOCK_SRC
instruction. The current selection can be queried with the instruction
INSN_CONFIG_GET_CLOCK_SRC.

Also, handle the INSN_CONFIG_RESET instruction to reset all the counters.
