[PATCH v2 07/14] staging: comedi: daqboard2000: rename acquisition control register macros

[Ian Abbott]

Rename the macros defining values for the acquisition control register
to avoid CamelCase, and to make it clearer which register they are
associated with.

v2: Shortened prefix from `DAQBOARD2000_` to `DB2K_`.
