The videobuf_queue_ops function vector is not declared constant, but
there's no need for the videobuf layer to ever change it.  Make it const
so that videobuf users can make their operations const without warnings.

On particularly weak signals, changing register 0xab after setting the
interleave mode will cause the FEC lock to get lost (while still holding the
EQ lock).  So remove the write entirely, which seems to have had no adverse
effect in either of my ClearQAM environments (and in particular resolves the
customer's reported issue).

Also flip around the order of the amhum optimization and the interleave setup
to be consistent with the windows driver, which has the side-benefit of doing
them both in the same call (since the amhum optimization can only be done once
the interleave setup).

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.

The sh51409 driver was only doing the QAM optimization a single time, and it
would only occur if you received a lock instantaneously after the tuning
request.  Restructure the code so that the optimization occurs once you reach
a signal lock.

Note that this depends on the caller polling for status, but we don't have
much choice at this point without an independent thread monitoring the lock
status.  Also, at this point pretty much every application polls for status
lock after doing the tune, so the likelihood of the optimization not occurring
in the real world is pretty low.

The state machine has also been reworked such that setting the interleave mode
is now a dependency of doing the QAM optimization.  Before both were mutually
exclusive, which was not consistent with the Windows driver.  We now have a
single state machine that controls both.

The changes as-is are only enabled for the HVR-1600.  Once the changes are
tested with some of the other boards, this change should be made generic and
the "_legacy" functions should be removed.

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.
