This patchset adds the required subdevice for supporting DI COS interrupts,
as well as introducing a driver-specific private data struct that will
make the COS interrupt operations much more straightforward and clean.

This board supports an interrupt that can be generated by an AND/OR
combination of 16 of the input channels.
Create a separate subdevice to handle this interrupt.
In doing this, this patch moves the apci1564_di_config() operation from
the digital input subdevice to this new subdevice, and also renames it to
make it more apparent that it is the config operation for the COS interrupt.

The addi-data drivers use send_sig() to let the user know when an
interrupt has occurred. The "standard" way to do this in the comedi
subsystem is to have a subdevice that supports asynchronous commands
and use comedi_event() to signal the user.
Remove the send_sig() usage in this driver.

The addi_private struct defined in addi-data/addi_common.h is very bloated
and contains many fields which addi_apci_1564 does not require. In the
interest of eventually removing this driver's dependency on
addi_common.h, we can create a private data struct specifically for
addi_apci_1564 containing only the fields it will actually use.

The idea behind this patch is that it will allow me to rewrite the
apci1564_cos_insn_config() function the same way that Hartley did for
addi_apci_1032.c, using new fields in this private struct. As such, lots
of the fields currently in the struct (all but amcc_iobase, to be precise)
are just temporary, and more fields will be introduced in subsequent
patches as needed. If this is not the best way to proceed then please
let me know and I will change my approach.

Since the original insn_config routine for the "DI" subdevice was quite
"bespoke" shall we say, I don't think it's worth adopting it "as is" for
the "COS" subdevice. Better just to remove it until it can be
implemented properly.

It would be nice to have an 'insn_bits' routine, even if the routine
just gives back a dummy data value for now.

Yeah, I had a feeling about that. I'll just rip it out and respin
this patch series to do that function properly.

I think in the next version of this patch, I will include a dummy
'insn_bits' function (so there will be no gap between introduction of
this subdevice and introduction of the insn_bits routine), and then I
will extend the patchset to include all of the other necessary
functions for the COS functionality in a later patch.

Thanks as always for the review, I'll get a new patchset out as soon as I can.

Please ignore this patchset completely, I am sending one out
momentarily that serves as its replacement.
Thanks,
