staging: comedi: das08: rename and rewrite DAS08_INTE
The `DAS08_INTE` macro contains a mask for the "INTE" bit in the control
register (except on "JR" boards). Setting it to 1 enables interrupts.
Setting it to 0 disables interrupts and clears the "IRQ" bit in the
status register. Rename the macro to `DAS08_CONTROL_INTE` and add a
comment. Also use the `BIT()` macro to define its value. (Note: the
driver does not currently enable interrupts.)
