[media] move parallel port/isa video drivers to drivers/media/parport/

We should keep just the I2C drivers under drivers/media/video, and
then rename it to drivers/media/i2c.

-/*
-	Supported devices:
-	*Lifeview FlyCam Supra (using the Philips saa7111a chip)
-
-	Does any other model using the w9966 interface chip exist ?
-
-	Todo:
-
-	*Add a working EPP mode, since DMA ECP read isn't implemented
-	in the parport drivers. (That's why it's so sloow)
-
-	*Add support for other ccd-control chips than the saa7111
-	please send me feedback on what kind of chips you have.
-
-	*Add proper probing. I don't know what's wrong with the IEEE1284
-	parport drivers but (IEEE1284_MODE_NIBBLE|IEEE1284_DEVICE_ID)
-	and nibble read seems to be broken for some peripherals.
-
-	*Add probing for onboard SRAM, port directions etc. (if possible)
-
-	*Add support for the hardware compressed modes (maybe using v4l2)
-
-	*Fix better support for the capture window (no skewed images, v4l
-	interface to capt. window)
-
-	*Probably some bugs that I don't know of
-
-	Please support me by sending feedback!
-
-	Changes:
-
-	Alan Cox:	Removed RGB mode for kernel merge, added THIS_MODULE
-			and owner support for newer module locks
