staging: comedi: ni_daq_700: remove exported symbols

This driver exports a number of functions with EXPORT_SYMBOL()
but nothing actually uses them. They also are not declared in
any header for use outside this module.

As stated in the comments, this driver was based on the 8255
driver so these exports are most likely the result of cut-and-
paste from the 8255 driver.

Remove all the EXPORT_SYMBOL() lines. If the exported function
is not used in the driver, remove the entire function as well.
If the function is used, make it static.

Also, make the dio700_cs_driver variable static since it's only
referenced in this file.

This quiets the following sparse warnings:

warning: symbol 'subdev_700_interrupt' was not declared. Should it be static?

pstore/ram: Probe as early as possible

Registering the platform driver before module_init allows us to log oopses
that happen during device probing.

This requires changing module_init to postcore_initcall, and switching
from platform_driver_probe to platform_driver_register because the
platform device is not registered when the platform driver is registered;
and because we use driver_register, now can't use create_bundle() (since
it will try to register the same driver once again), so we have to switch
to platform_device_register_data().

Also, some __init -> __devinit changes were needed.

Overall, the registration logic is now much clearer, since we have only
one driver registration point, and just an optional dummy device, which
is created from the module parameters.

CONFIG_COMEDI_PCI_DRIVERS to make sure the 8255 driver
