Embed the video_device struct to simplify the error handling and in
order to (eventually) get rid of video_device_alloc/release.

interface driver
This change hooks up the ivtv PCM capture stream to the ivtv-alsa interface
driver. This is all that should be needed for basic CX23415/CX23416 PCM
audio capture to be available via ALSA device nodes.

This is a cut-and-paste port of the cx18-alsa driver to
create an ivtv-alsa interface module for the ivtv driver.
It is not actually hooked-up to the PCM stream DMA buffers
from the ivtv driver yet. That will be done in a coming change,
since that portion is so very different from the cx18 driver.
This code has all or more of the bugs and shortcomings of the
cx18-alsa interface driver: inconsistent use of itvsc->slock,
ivtv-alsa-mixer.c is dead code, assumes 48 ksps regardless
of the actual setting of the audio capture, problems with
proper struct ivtv and struct ivtv_stream housekeeping,
struct ivtv_open_id.v4l2_fh abuse, and $DIETY knows what else.

Rename all PCI drivers with their own directory under
drivers/media/video into drivers/media/pci and update the
