[media] it913x: fix firmware loading errors

On some systems the device does not respond or give obscure values after cold,
warm or firmware reboot.

This patch retries to get chip version and type 5 times. If it
fails it applies chip version 0x1 and type 0x9135.

This patch does not fix warm cycle problems from other operating
systems and indeed the reverse applies. Users should power off cold boot.

[media] dvb_frontend: regression fix: userspace ABI broken for xine

The commit e399ce77e6e has broken the DVB ABI for xine:

The problem is that xine is expecting every event after a successful
FE_SET_FRONTEND ioctl to have a non-zero frequency parameter, regardless
of whether the tuning process has LOCKed yet. What used to happen is
that the events inherited the initial tuning parameters from the
FE_SET_FRONTEND call. However, the fepriv->parameters_out struct is now
not initialised until the status contains the FE_HAS_LOCK bit.

You might argue that this behaviour is intentional, except that if an
application other than xine uses the DVB adapter and manages to set the
parameters_out.frequency field to something other than zero, then xine
no longer has any problems until either the adapter is replugged or the
kernel modules reloaded. This can only mean that the
fepriv->parameters_out struct still contains the (stale) tuning
information from the previous application.

[media] marvell-cam: Remove broken "owner" logic

The marvell cam driver retained just enough of the owner-tracking logic
from cafe_ccic to be broken; it could, conceivably, cause the driver to
release DMA memory while the controller is still active.  Simply remove the
remaining pieces and ensure that the controller is stopped before we free
things.

'videodev' to present when the 'webcam_bind' routine is called,
so 'videodev' should be available as early as possible.

Now, when 'g_webcam' is built as a module (i.e. not a part of
kernel) the late availability of 'videodev' is OK, but if
'g_webcam' is built statically as a part of the kernel,
the kernel crashes (a sample crash dump using Designware 2.0 UDC
is provided below).

Ryley fuond out that the best value for his Elgato stick is indeed the current
default value 0xC0.

Instead, my stick is not capable of tuning VHF channels with 0xC0. With 0x80,
VHF works but the tuner sensitivity with the portable antenna is poor.
Instead, the value 0xA0 works with VHF and also gives good performance with
both the rooftop and the portable antenna.

So we concluded that devices built on the reference design work best with 0xA0,
while custom designs (Elgato, PCTV) seem to require 0xC0.

[media] STV0288 increase delay between carrier search

The current delay of 30uS is too short to recover any carrier.

In the lmedm04 driver delays were added to overcome carrier lock
problems. The typical delay was 30mS (2 x 15ms register write
0x2c and read 0x24).

Other drivers that use STV0288 don't appear to have any delay are
likely to have also suffered this problem.

- The radio_nr module parameter must be part of the actual radio driver,

  50-150.
- Add hardware frequency seek support.
- Fix broken rxsubchans/audmode handling.
- The application can now select between stereo and mono.
- Support polling for control events.
- Add V4L2 priority handling.
