Clarify whether job_ready returns false because the context is on hold, waiting
for new input buffers, whether there are not enough input buffers to fill two
into the bitstream, or whether there is not enough data in the bitstream buffer
for the bitstream reader hardware to read a whole frame.

If userspace doesn't properly separate the bitstream input into
individual frames (which may happen for example on slightly
corrupted streams) the CODA hardware may decode more frames
than we expect. We already log an error in this case, but it's
also necessary to adjust the sequence offset. Otherwise we
spam the log with a sequence number mismatch on every frame
frame after the unexpected one.

The MFC driver has two controls, DISPLAY_DELAY and DISPLAY_DELAY_ENABLE
that allow forcing the decoder to return a decoded frame sooner
regardless of the order. The added support for firmware version 6 and
higher was not taking into account the DISPLAY_DELAY_ENABLE boolean.
Instead it had a comment stating that DISPLAY_DELAY should be set to a
negative value to disable it. This is not possible since the control
range is from 0 to 65535. This feature was also supposed to be disabled
by default in order to produce frames in display order.

These drivers haven't been tested in a long, long time. The hardware is
ancient and hopelessly obsolete. These drivers also need to be converted
to newer media frameworks but due to the lack of hardware that's going
to be impossible. In addition, cheaper and vastly better hardware is
available today.
These drivers are already deprecated, so now remove them altogether.

This driver hasn't been tested in a long, long time. The company that made
this chip has gone bust many years ago and hardware using this chip is next
to impossible to find.
This driver needs to be converted to newer media frameworks but due to the
lack of hardware that's going to be impossible. Since cheap alternatives are
easily available, there is little point in keeping this driver alive.
This driver is already deprecated, so now remove it altogether.

All known old firmware firmware formats are downloaded using 8 byte

With recent v4l-utils library (>=0.9.1), that uses "bytesperline" for
pixel format conversion, the result is a wrong jerky image.

Add support in the PS3 Eye driver for QVGA capture at higher
frame rates: 187, 150, and 137 FPS. This functionality is valuable
because the PS3 Eye is popular for computer vision projects and no
other camera in its price range supports such high frame rates.
Correct a QVGA mode that was listed as 40 FPS. It is really 37 FPS
(half of 75 FPS).
Tests confirm that the nominal frame rates are achieved.

Add support for the larger fifo found on sun5i and sun6i, having a separate
compatible for the ir found on sun5i & sun6i also is useful if we ever want
to add ir transmit support, because the sun5i & sun6i version do not have
transmit support.
Note this commits also adds checking for the end-of-packet interrupt flag
(which was already enabled), as the fifo-data-available interrupt flag only
gets set when the trigger-level is exceeded. So far we've been getting away
with not doing this because of the low trigger-level, but this is something
which we should have done since day one.
