[media] tvp5150: Add video format registers configuration values

The tvp5150 video decoder has two operation modes to configure the video
standard used.

If auto-switch mode is enable, the device can sense the signal and detect which
video standard the device is operating. Also the device can be forced to use a
user defined video standard.

Each operation mode uses a different register and the bitmask values to
represent each standard is different.

So we add video standard constants for both autoswitch and no-autoswitch mode.

that the driver was never intended to work without these enabled,

[media] em28xx: replug locking cleanup

Simplifies the locking by moving the em28xx_init_extension() call until
em28xx_usb_probe() has finished with the dev->lock mutex. It therefore
makes the second and subsequent "plugging" events logically identical to
the first "plugging" event when the em28xx-dvb and em28xx-alsa modules
must be loaded (i.e. registered).

Basically, em28xx_usb_probe() requests that em28xx-dvb be loaded and
also triggers udev to initialise the V4L2 devices. These two events are
serialised by the dev->lock mutex but the order that they happen in is
undefined. But this has always been the case anyway.

em28xx_release_resources(), and then passed to the em28xx_close_extension()
function so that all extensions could run their fini() operations. However, this
left a (brief, theoretical, highly unlikely ;-)) window between these two calls
during which a new module could call em28xx_register_extension(). The result
would have been that the em28xx_usb_disconnect() function would also have passed
the device to the new extension's fini() function, despite never having called
the extension's init() function.

This patch also restores em28xx_close_extension()'s symmetry with
em28xx_init_extension(), and establishes the property that every device in the
device list must have been initialised for every extension in the extension list.

[media] v4l2: Add polarity flag definitions for the parallel bus FIELD signal

FIELD signal is used for indicating frame field type to the frame grabber
in interlaced scan mode, as specified in ITU-R BT.601 standard.
In normal operation mode FIELD = 0 selects Field1 (odd) and FIELD = 1
selects Field2 (even). When the FIELD signal is inverted it's the other
way around.

Add corresponding flags for configuring the FIELD signal polarity,
V4L2_MBUS_FIELD_EVEN_HIGH for the standard (non-inverted) case and
V4L2_MBUS_FIELD_EVEN_LOW for inverted case.

Also add a comment about usage of V4L2_MBUS_[HV]SYNC* flags for

[media] media: Fix a UVC performance problem on systems with non-coherent DMA

The UVC driver uses usb_alloc_coherent() to allocate DMA data buffers.
On systems without coherent DMA this ends up allocating buffers in
uncached memory. The subsequent memcpy's done to coalesce the DMA
chunks into contiguous buffers then run VERY slowly. On a MIPS test
system the memcpy is about 200 times slower. This issue prevents the
system from keeping up with 720p YUYV data at 10fps.

The following patch uses kmalloc to alloc the DMA buffers instead of
usb_alloc_coherent on systems without coherent DMA. With this patch
the system was easily able to keep up with 720p at 10fps.
