Currently the platform data for the ad7793 consist just out of the raw default
register settings. This has some downsides, for one we actually don't want to
make all bits configurable and secondly not all register settings are actually
valid. This patch exposes all the options which should be configurable via
platform data as induvidual platform data struct fields. This also allows us to
document the different settings via proper kernel doc.

We changed the sizeof() statements in 429ccf05 "staging:panel: Fixed
coding conventions." so that they could fit inside the 80 character
line limit.  Unfortunately, the new sizeof() statements are a smaller
size.  This reverts it.

There isn't a nice way to stay within the 80 character limit without
a re-work so I've gone over.

This board supports two interrupt sources:

VCC : detects when the external supply voltage drops below 5V
CC  : over temperature diagnostic

Currently the interrupt support is tied into the digital output
subdevice. It's also broken since it does not follow the comedi
API.

Create a new digital input subdevice to handle the interrupts.

The only data in addi_private used in this driver is:

tsk_Current - used with send_sig to signal userspace when an interrupt
has occurred. Interrupt support in this driver does not follow the
standard comedi API so this functionality is currently broken. This
will be addressed.

b_OutputMemoryStatus - used in the addi-data "common" code to enable
reading of the eeprom. Eeprom support is not needed by this driver
and has been removed.

Since this data is not needed, remove the use of struct addi_private.
