This driver was originally copied from the 8255 driver. The 8255
uses a callback function to handle the io operations to the device.
In this driver, the callback adds unneeded complexity.
The CALLBACK_ARG for this driver is always 'dev->iobase' and the
CALLBACK_FUNC is always 'subdev_700_cb'.
The callback function is also overly complex for this driver.
It takes a 'dir' parameter to determine if the io is a write or
read, a 'port' parameter that is not used, a 'data' parameter
that is only used for writes, and an 'arg' which is the iobase
of the device.
Unwind all of it and just put the outb()/inb() call in the code
where needed.
This allows getting rid of the private data completely. Refactor
the code based on it's removal.

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:

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.

ZSMALLOC is tristate, but the code has no MODULE_LICENSE and since it
depends on GPL-only symbols it cannot be loaded as a module. This in
turn breaks zram which now depends on it. I assume it's meant to be
Dual BSD/GPL like the other z-stuff.
There is also no module_exit, which will make it impossible to unload.
Add the appropriate module_init and module_exit declarations suggested
