[PATCH 1/2] staging: comedi: addi_apci_1564: remove use of devpriv->iobase

devpriv->iobase is currently being used to hold the iobase address used to
read/write the board's registers. The same address is stored in the
comedi_device dev->iobase. We use that instead. The eventual goal is to
decrease the driver's use of the struct addi_private, so that it may
eventually use a much slimmer specialized private struct instead, as the
other addi_apci_* drivers do.

This is a (small) first patchset for my more complete cleanup of
addi_apci_1564 driver. Hartley, I'd appreciate any review you have
wrt these specific patches, but also whether I have chosen a good place
to start.
