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.)
