This patch converts the em28xx driver over to videobuf2.  It is
likely that em28xx_fh can go away entirely, but that will come in
a separate patch.

The sliced VBI support in the tvp5150 is completely broken. And there is no
support for the saa7115 sliced VBI implementation in the em28xx driver. So
we remove the sliced VBI support completely.
It should be possible to get it to work with the tvp5150, but that will
require someone to really dig into that driver.

The ir-i2c-kbd already adds I2C IR before the name. The way it is,
the devices are named as:
	"i2c IR (i2c IR (EM2840 Hauppaug"
With is ugly and incorrect. After this patch, it is now properly
displayed as:
	"i2c IR (WinTV USB2)"

If the device has an I2C IR, em28xx-rc should be loaded by default,
except if the user explicitly requested to not load, via modprobe
option.

The em28xx-input is used by 3 different types of input devices:
	- devices with buttons (like cameras and grabber devices);
	- devices with I2C remotes;
	- em2860 or latter chips with RC support embedded.
When the device has an I2C remote, all it needs to do is to call
the proper I2C driver (ir-i2c-kbd), passing the proper data to
it, and just leave the code.
Also, button devices have its own init code that doesn't depend on
having an IR or not (as a general rule, they don't have).
So, move its init code to fix bugs introduced by earlier patches
that prevent them to work.
