cover staging: comedi: addi_apci_1564: miscellaneous cleanups

This patchset removes an uncorrect and unneeded insn_config operation, strips out remaining in-driver watchdog subdevice code, and cleans up the driver's register map defines.

PATCH 1/3 staging: comedi: addi_apci_1564: remove apci1564_do_config

The DO config function served the purpose of configuring the diagnostic interrupts for the board. As the driver currently does not support diagnostic interrupts, the digital output subdevice does not need an insn_config operation and this function can be safely removed.

PATCH 2/3 staging: comedi: addi_apci_1564: Remove in-driver watchdog support code

In reply to Chase Southwood

Starting with commit 1496e5961113 ("staging: comedi: addi_apci_1564: use addi_watchdog module to init watchdog subdevice"), this driver uses the addi_watchdog module to provide support for the watchdog subdevice. Any remaining watchdog code in-driver can and should be removed.

This will also make future work on the timer and counter subdevices easier.

PATCH 3/3 staging: comedi: addi_apci_1564: tidy register map defines

In reply to Chase Southwood

This commit performs a final tidying of the register map defines, bringing them to a state that is ready for merging into addi_apci_1564.c when the time comes. Actions performed include:

*Removes the APCI1564_ADDRESS_RANGE macro, which is no longer needed/used. *Renames the APCI1564_DIGITAL_OP_{VCC,CC}_INTERRUPT_{ENABLE,DISABLE} macros to shorter names which are more consistent with the digital input interrupt macros.
*Fixes a typo in a comment (dev>iobase changed to dev->iobase). *Renames the APCI1564_TCW_* macros to APCI1564_COUNTER_* names to more accurately reflect that they are only offsets to counter registers (since only the counters are offset from dev->iobase).
