eeprom configuration.
The em28xx actually has a register that tells the driver what the maximum
packet size is (based on a value programmed into the eeprom). Make use of
that register instead of assuming a hardcoded value of 564 (since 564 is not
correct for devices that do QAM such as the KWorld 340u).
Note that for now the em2874 code isn't there, falling back to the 564 value,
however this is not a problem since there are not any em2874 based devices in
the current v4l-dvb tree).
Thanks to Jarod Wilson for detecting the initial problem and figuring out that
the isoc configuration was wrong for his device.

Essentially if a snd_em28xx_capture_trigger() stop followed by a snd_em28xx_capture_trigger() start would not yield any
data because there was some logic put in with an adev->shutdown variable which did not seem warranted in my humble opinion.
It would cause snd_em28xx_capture_trigger start never to start up the audio stream until the device was closed and
reopened again. Upon re-opening the device adev->shutdown is reset and audio data would again flow.

Some devices require different setups on struct_audio. Due to that, we
may need to change some fields at dev.adev during device probe. So, this
patch moves the dynamic memory allocation of adev at em28xx-alsa to the
dynamic allocation of struct em28xx dev that happens during device
probe.

Introduce a struct v4l2_file_operations for v4l2 drivers.
Remove the unnecessary inode argument.
Move compat32 handling (and llseek) into the v4l2-dev core: this is now
handled in the v4l2 core and no longer in the drivers themselves.
Note that this changeset reverts an earlier patch that changed the return
type of__video_ioctl2 from int to long. This change will be reinstated
later in a much improved version.

The Pinnacle 80e cannot be supported since Micronas yanked their driver
support for the drx-j chipset at the last minute. Remove the device profile
since it cannot work without the drx driver and it being there is only likely
to confuse people into thinking the device is supported but not working.

Now, just two routines are enough for analog: the first one configs the analog
part and register V4L2 devices, and the second one release analog devices.

em28xx-video were holding several code that are not specific to V4L2
interface.
This patch moves the core code for em28xx-core, and usb probing code
into em28xx-cards.
This opens the possibility of breaking em28xx into a core module and a
V4L2 module, loaded only on devices that have analog interfaces.
Some cleanup may be done at em28xx-cards to optimize the config code.

Replaces all occurrences of em28xx_write_regs_req() and em28xx_write_reg()

The previous patches removed XCLK and I2C magic. Now, we finally know
what those registers do. Also, only a very few cards need different
setups for those.
Instead of keeping the setups for those values inside the per-device
hack magic switch, move the uncommon values to the board-specific
struct, and have a common setup for all other boards.
So, almost 100 lines of hacking magic were removed.
A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk
were set, without taking any care about not overriding a previous xclk setup.

AC97 devices provide several input and outputs. However, before this
patch, em28xx device weren't properly allowing the usage of ac97
possible combinations. Also, several input volumes were left untouched,
instead of making sure that the volumes were set on mute state.
This patch improves support for ac97 devices by allowing to use any
inputs, and making sure that unused inputs are set on mute state.
Yet, some work is still needed to select the AC97 output.

The first em28xx were based on i2c IR's. However, some newer designs
are coming with a polling-based IR. Those are done by reading a register
set at em28xx.
This patch adds core polling support for those devices. Later patches will
add support for some device-specific IR's.
This patch adds the same basic IR polling code used by bttv, cx88 and saa7134, and
shares the common getkey masks defined at ir-common.
