changeset da8ec560e3b4 ("[media] ivtv: implement new decoder command
ioctls") implemented proper support for mpeg audio and video control
at V4L2 API. Since then, the usage of the the DVB APIs is deprecated.
However, we never actually marked it as deprecated nor provided any
way to disable it. Let's do it now.
This patch prepares for the removal of this bad usage on a couple
of Kernel versions.

We are burrying direct access to MTRR code support on
x86 in order to take advantage of PAT. In the future, we
also want to make the default behavior of ioremap_nocache()
to use strong UC, at which point the use of mtrr_add() on
those systems would make write-combining void.
In order to help both enable us to later make strong
UC default and in order to phase out direct MTRR access
code, port the driver over to the arch_phys_wc_add() API
and annotate that the device driver requires systems to
boot with PAT disabled, with the 'nopat' kernel parameter.
This is a workable compromise given that the hardware is
really rare these days, and perhaps only some lost souls
stuck with obsolete hardware are expected to be using this
feature of the device driver.

Remove the (somewhat meaningless?) dependency on EXPERIMENTAL for the
ivtv-alsa driver. Revise the Kconfig help text to be a little clearer for
the lay person, while we are here.

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
building system.
