It seems that the old developer is no longer with the company producing
this device, and the company has no plans on getting this out of the
staging directory at all, so let's drop the driver for now as it's
pretty much abandonded.
If someone want to support this and get it out of staging, we can easily
revert this change and bring it back.

The existing implementation for doing DMA via asynchronous IO didn't
work and there was no longer a use-case for it. Removed it.
Fixed a few checkpatch warnings about too-long lines and extraneous
braces in the process.

Previously the next card number was assigned from a static int local
variable. Replaced it with an IDA. Avoids the assignment of ever-
increasing card-numbers by allowing them to be reused.
Updated TODO.
Corrected format-specifier for unsigned pcard->card_num.

On error, kp2000_probe_cores just returned an error without freeing
resources which had previously been allocated. Added the missing
clean-up code.
Updated TODO.

These drivers have been outside of the kernel tree since the 2.x days,
and it's time to bring them into the tree so they can get properly
cleaned up.
This first dump of drivers is based on a tarball Matt gave to me, minus
an odd "dma" driver that I could not get to build at all. I renamed a
few files, added the proper SPDX lines to it, added Kconfig entries and
tied it into the kernel build. I also fixed up a number of initial
obvious kernel build warnings, but left the odd bitfield warning that
gcc is spitting out, as I'm not quite sure what to do about that.
There's loads of low-hanging coding style cleanups in here for people to
start attacking, as well as the more obvious logic and api cleanups as
well.
