This patch adds support for the UB435-Q V2. You might need to
use the device once with the Windows driver provided by KWorld
in order to permanently reprogram the device descriptors. Thanks
to Jarod Wilson for the initial attempt at adding support for this
device.

The em28xx driver only calls subdevices' .s_power() method to power them
down, relying on the hardware to wake up automatically, which is usually
the case with tuners. This was acceptable with the old .standby() method,
but is wrong with .s_power(). Fixing the driver would be difficult due to
a broad supported hardware base. Instead this patch makes use of the
unbalanced_power soc-camera subdevice flag to tell the ov2640 driver to
balance calls to v4l2_clk_enable() and v4l2_clk_disable() internally.

The GPIO register caching is the result of wrong assumptions and incomplete
knowledge about the GPIO registers and their functionality.
Today, we know that it is not needed.
It is also limited to a single register and therefore incomplete (newer chips
are using multiple registers).
Instead of extending the caching, get rid of it, because it has no real
benefits and just bloats/complicates the code.

Chip id 18 is used by the em2710 and em2820.
The current code assumes that if the device is a camera, the chip is an em2710
and an em2820 otherwise.
But it turned out that the em2820 is also used in camera devices.

Fortunately both variants are using different generic USD IDs which give us a

Sensor detection and initialization/configuration are currently mixed together.
This works as long as all devices with a particular sensor are working with the
same board configuration. In the long run, this will be not sufficient, so
separate these both steps to make the code more flexible and future proof.
This also makes the code more consistent, because the initialization of the
MT9V011 sensor subdevice is already separated.

The current board hint code is mixed together with the sensor detection and
initialization code. It actually selects a board depending on the detected
sensor type only, with the result that 3 of the 6 webcam boards are currently
dead.
Separate it and move it to em28xx_hint_board() which already contains the board
hints for analog capturing+TV and DVB devices.
This way, we have all board hints at a common place which makes it easier
to extend the code and reduces the risk of regressions.
It also makes it possible again to use the boards EM2750_BOARD_DLCW_130,
EM2820_BOARD_VIDEOLOGY_20K14XUSB and EM2860_BOARD_NETGMBH_CAM (using the module
parameter "card").

The webcam "SpeedLink VAD Laplace" (em2765 + ov2640) uses a special algorithm
for i2c communication with the sensor, which is connected to a second i2c bus.
We don't know yet how to find out which devices support/use it.
It's very likely used by all em25xx and em276x+ bridges.
Tests with other em28xx chips (em2820, em2882/em2883) show, that this
algorithm always succeeds there although no slave device is connected.
The algorithm likely also works for real i2c client devices (OV2640 uses SCCB),
because the Windows driver seems to use it for probing Samsung and Kodak
sensors.
