[RFC PATCH] cx231xx: Add support for Kworld UB430 AF

[Mauro Carvalho Chehab <mchehab@redhat.com>]

This device seems to be close to Pixelview design. Probably, the remote controller
is different.

Also, AGC selection doesn't seem to use any GPIO writing, at least from the logs
I got from Márcio.

PS.: This patch is to be applied against staging/for_v2.6.38 branch at the main tree:
	http://git.linuxtv.org/media_tree.git?a=shortlog;h=refs/heads/staging/for_v2.6.38

Márcio,

Could you please test it? It would be wonderful if you could test the new IR support. You
should uncomment the code bellow (commented with #if 0), and, eventually, you'll need to
play with RC keymaps.

I'd appreciate if you could send me some parsed logs for both analog and digital
modes. I've improved the cx231xx-specific parser at v4l-apps, in order to catch GPIO
changes. So far, I didn't get any trial to change GPIO bits on your logs (nor on my logs with 
Pixelview).

When I have more time, I'll try to do more tests on it.
