The HVR-1600 doesn't use the standard mechanism for computing the gain when
in QAM mode, instead always forcing it to be 0x02. Provide the ability to
override the algorithm on a per-board basis.
This change results in an improvement of 0.4-0.6 dB for QAM tuning.

Perform some optimization of the register configuration based on a trace
of the HVR-1600 Windows i2c traffic (and consultation with Steven Toth).
Note that some of these values may be able to be moved into the common driver,
but I am holding off on that until they can be tested with other boards.

It seems that some patch broke alt modprobe parameter. Fix it to allow
changing alternate interfaces during module load and at runtime.
If changed during runtime, you'll need to stop a and restart stream for
the parameter to be used.

All PAC7311 specific functions remain in pac7311.c. All PAC7302 specific
functions are moved to pac7302.c. The USB device table is also divided into
two parts. This makes it possible to remove the sensor specific decisions
from different functions and also remove sensor infromation from the USB
device table.
The common functions are just copied to both subdrivers. These common
functions can be separated later to a common file or helper module.

Upcoming I2C v4l2_subdev drivers need a way to control the subdevice
power state from the core. This use case is already partially covered by
the tuner s_standby operation, but no way to explicitly come back from
the standby state is available.
Rename the tuner s_standby operation to core s_power, and fix tuner
drivers accordingly. The tuner core will call s_power(0) instead of
s_standby(). No explicit call to s_power(1) is required for tuners as
they are supposed to wake up from standby automatically.

I do not think it makes sense any longer for ir-kbd-i2c to reject
devices at unknown I2C addresses. The caller can provide all the
details about how the device should be handled. Having to add new
addresses to ir-kbd-i2c so that they aren't rejected is a pain we
don't need. Unsupported devices will be spotted a few lines later
anyway.
This already lets us unlist 2 addresses (0x7a and 0x2d) for which
handling details are always provided by the caller (saa7134-input).
Hopefully we can remove more in the future.

Google is pretty clear that the HVR 1110 IR chip is always at address
0x71 and the BeholdTV IR chip is always at address 0x2d. This
completes the list of IR device addresses for the SAA7134-based
adapters, and we no longer need to probe any of them.

The i2c core prevents us from probing I2C address 0x7a because it's
not a valid 7-bit address (reserved for 10-bit addressing.) So we must
stop probing this address, and explicitly list all adapters which use
it. Under the assumption that only the Upmost Purple TV adapter uses
this invalid address, this fix should do the trick.

Recent fixes to the em28xx and saa7134 drivers have been overzealous.
While the ir-kbd-i2c platform data indeed needs to be persistent, the
struct i2c_board_info doesn't, as it is only used by i2c_new_device().
So revert a part of the original fixes, to save some memory.
