Demod lock flags are derived from demod state machine states. States

fully locked and streaming. Naturally smaller state numbers means
there is some partial locks.
Define now state 10 as missing synch and lock.

[media] adv7180: Do implicit register paging
The ad7180 has multiple register pages which can be switched between by
writing to a register. Currently the driver manually switches between pages
whenever a register outside of the default register map is accessed and
switches back after it has been accessed. This is a bit tedious and also
potential source for bugs.
This patch adds two helper functions that take care of switching between
pages and reading/writing the register. The register numbers for registers
are updated to encode both the page (in the upper 8-bits) and the register
(in the lower 8-bits) numbers.
Having multiple pages means that a register access is not a single atomic
i2c_smbus_write_byte_data() or i2c_smbus_read_byte_data() call and we need
to make sure that concurrent register access does not race against each
other.

[media] coda: issue seq_end_work during stop_streaming
This patch queues seq_end_work and flushes the queue during stop_streaming
and clears the ctx->initialized flag. This allows to start streaming again
after stopping streaming without releasing the context.

[media] coda: adjust sequence offset after unexpected decoded 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.

[media] s5p-mfc-v6+: Use display_delay_enable CID
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.
