The reset function for this driver is a bit of a mess; clean it up to
ensure that it is functioning properly.

2: *Changed order of register accesses for digital input registers back to
original ordering.
*Removed read of digital output status register and reordered the accesses
of digital output registers to agree with the order found in addi_apci_2032.
*Fixed copy/paste error in the counter register reset lines.

3: *Returned the reset callback to the boardinfo...oops.
*Don't write APCI1564_DO_IRQ_REG (it's read only).
*Don't clear counter reload values...counters have already been
disabled.

4: Leave this in hwdrv_apci1564.c for now (it can be moved after separating
this driver from addi_common.c)

NB: This patch has been renamed in this version. It was previously known
as "staging: comedi: addi_apci_1564: fixup and absorb apci1564_reset()"
