There was a bug where enumerating the i2c for devices would result in false
positives. The root of the issue was the scanning was using SMBUS_QUICK
messages, which are zero length write requests (which our i2c adapter
implementation didn't handle). Because we never strobed any bytes onto the
bus, the status register would still contain the value from the previous
request.

V4L/DVB (11067): au0828: workaround a bug in the au0828 i2c handling
There is an issue related to the i2c clock for addressing the xc5000. The
au0828 chip does not support clock stretching, which the xc5000 makes use of.
This results in cases where we silently get back garbage in i2c read
operations. To work around this issue until we slow down the i2c clock when
talking with that specific device.
This was not an issue before we had analog support because we never needed to
enumerate the i2c bus, and digital tuning never actually needed to perform
read operations against the xc5000.
