Subject: [PATCH v3 3/5] staging: comedi: addi_apci_1564: introduce apci1564_private struct

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.
