[PATCH 3/8] staging: comedi: dmm32at: remove forward declarations 2

[H Hartley Sweeten <hartleys@visionengravers.com>]

Move the dmm32at_ns_to_timer() and dmm32at_setaitimer() functions
to remove the need for the remaining forward declarations.

Also, make dmm32at_setaitimer() static, it's only referenced in
this file.
