[media] cx231xx: use TRANSFER_TYPE enum for cleanup

Most calls to cx231xx_capture_start() already use the values from
TRANSFER_TYPE, but cx231xx_capture_start() and
cx231xx_initialize_stream_xfer() were hand coding the values.
Use the named values (81 is never passed in), and simplify
cx231xx_capture_start(), as the switch statements were identical and
pcb_config->config_num is a u8, so any non-zero config got the same
result.

[media] media: only show V4L devices based on device type selection

After this patch, the MEDIA*_SUPPORT will be used as a filter,

[media] media: Remove VIDEO_MEDIA Kconfig option

In the past, it was possible to have either DVB or V4L2 core
as module and the other as builtin. Such config never make much
sense, and created several issues in order to make the Kconfig
dependency to work, as all drivers that depend on both (most
TV drivers) would need to be compiled as 'm'. Due to that,
the VIDEO_MEDIA config option were added.

Instead of such weird approach, let's just use the MEDIA_SUPPORT
=y or =m to select if the media subsystem core will be either
builtin or module, simplifying the building system logic.

Also, fix the tuners configuration, by enabling them only if
a tuner is required. So, if just webcam/grabbers support is
selected, no tuner option will be selected. Also, if only digital
TV is selected, no analog tuner support is selected.

That removes the need of using EXPERT customise options, when
analog TV is not selected.

[media] i2c: Export an unlocked flavor of i2c_transfer

Some drivers (in particular for TV cards) need exclusive access to
their I2C buses for specific operations. Export an unlocked flavor
of i2c_transfer to give them full control.

The unlocked flavor has the following limitations:
* Obviously, caller must hold the i2c adapter lock.
* No debug messages are logged. We don't want to log messages while
  holding a rt_mutex.
* No check is done on the existence of adap->algo->master_xfer. It
  is thus the caller's responsibility to ensure that the function is
  OK to call.

modes from setting of the frequency until VIDIOC_S_TUNER was called.
It then forced the hardware to use the mode requested by the user.

The mem2mem_testdev allows multiple instances to be opened in parallel.
Source and destination queue data are being shared between all
instances, which can lead to kernel oops due to race conditions (most
likely to happen inside device_run()).

[media] DVB: stb0899: speed up getting BER values

stb0899_read_ber() takes 500ms (half a second!) to deliver the current
BER value. Apparently it takes 5 subsequent readings, with a 100ms pause
between them (and even before the first one). This is a real performance
brake if an application freqeuently reads the BER of several devices.
The attached patch reduces this to a single reading, with no more pausing.
I didn't observe any negative side effects of this change.
