staging: comedi: me4000: fix 8254 timer programming

As pointed out by Ian Abbott, the i8254_load() function does not
use the I8254_MODE* values to specify the "mode".

Refactor the 8254 timer programming to use the i8254_set_mode()
and i8254_write() helpers instead of i8254_load(). This allows
us to use the I8254_MODE* defines to clarify the code.

Also, use the CR_CHAN() macro to make sure the only the channel is
used in the insh->chanspec to specify the counter number.
