Noticed when doing the audio support for the Pinnacle PCTV HD Ultimate 808e
that the modes were incorrect (the 808e uses I2S in 5 sample mode)

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.

Correct problem introduced during the board refactoring where the XCLK
frequency would get zero'd out. The sequence of events was as follows:
em28xx_pre_card_setup() called em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration
em28xx_pre_card_setup() would set the dev->board.xclk if not set
em28xx_pre_card_setup() would set the XCLK register based on dev->board.xclk
...
em28xx_card_setup() would call em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration (clearing out
value of dev->board.xclk set in em28xx_pre_card_setup)
...
em28xx_audio_analog_set() sets the XCLK register based on dev->board.xclk
(which now contains zero)
The change sets the default XCLK and I2C Clock fields in the board definition
inside of em28xx_set_model() so that subsequent calls do not cause the
values to be overwritten.

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.
After this patch, it will be easier to transform em28xx-video into an em28xx
extension, loaded only on 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.

Changes/fixes on em28xx dev->lock:
- em28xx_init_dev() were unlocking without a previous lock;
- some read ioctls need to lock after the removal of KBL, since a write
may be happening at the same time an ioctl is reading;
- keep the device locked during all device initialization;
- lock/unlock while reading/writing registers.

vidioc_try_fmt_vid_cap() just checks if a given resolution is supported.
It doesn't touch on struct em28xx device descriptor. so, there's no need
to lock.
While there, use unlikely() for those values that aren't likely to
occur.

em28xx devices generally get hot when xc3028 tuner is powered on. This
patch solves this by turning power off when the device is not used, at the
expense of having a higher load time, when calling a TV application.
Since firmware load happens on 1 or 2 seconds on most devices, this is not a pain.
Also, it helps to save the planet by saving some power :)

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.
