[media] smiapp: Export OF module alias information

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So technically there's no need for a driver to export
the OF table since currently it's not used.

In fact, the I2C device ID table is mandatory for I2C drivers since
a i2c_device_id is passed to the driver's probe function even if the
I2C core used the OF table to match the driver.

And since the I2C core uses different tables, OF-only drivers needs to
have duplicated data that has to be kept in sync and also the dev node
compatible manufacturer prefix is stripped when reporting the MODALIAS.

To avoid the above, the I2C core behavior may be changed in the future
to not require an I2C device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table to prevent
breaking module autoloading if that happens.

[media] s5p-jpeg: add support for 5433

JPEG IP found in Exynos5433 is similar to what is in Exynos4, but
there are some subtle differences which this patch takes into account.

The most important difference is in what is processed by the JPEG IP and
what has to be provided to it. In case of 5433 the IP does not parse
Huffman and quantisation tables, so this has to be performed with the CPU
and the majority of the code in this patch does that.

A small but important difference is in what address is passed to the JPEG
IP. In case of 5433 it is the SOS (start of scan) position, which is
natural, because the headers must be parsed elsewhere.

There is also a difference in how the hardware is put to work in
device_run.

Data structures are extended as appropriate to accommodate the above
changes.

[media] go7007: Fix returned errno code in gen_mjpeghdr_to_package()

The driver is using -1 instead of the -ENOMEM defined macro to specify
that a buffer allocation failed. Since the error number is propagated,
the caller will get a -EPERM which is the wrong error condition.

Also, the smatch tool complains with the following warning:

[media] s5c73m3: Export OF module alias information

The SPI core always reports the MODALIAS uevent as "spi:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: SPI id table or OF match table).

So drivers needs to export the SPI id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.

But this means that OF-only drivers needs to have both OF and SPI id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same SPI device name for example.

To avoid the above, the SPI core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

This is a preparation for a change to the type of v4l2 timestamps.
v4l2_get_timestamp() is a helper function that reads the monotonic
time and stores it into a 'struct timeval'. Multiple drivers implement
the same thing themselves for historic reasons.
