The SMPTE-2084 transfer functions maps to the luminance range of
0-10000 cd/m^2. Other transfer functions use the traditional range of
0-100 cd/m^2.
I didn't take this into account so the luminance was off by a factor of
100.
Since qv4l2 made the same mistake in reverse I never noticed this until
I tested with actual SMPTE-2084 video.

Passing uninitialized flags into device_prep_interleaved_dma is clearly
a bad idea, and we get a compiler warning for it:
drivers/media/platform/omap/omap_vout_vrfb.c: In function 'omap_vout_prepare_vrfb':
drivers/media/platform/omap/omap_vout_vrfb.c:273:5: error: 'flags' may be used uninitialized in this function [-Werror=maybe-uninitialized]
It seems that the OMAP dmaengine ignores the flags, but we should
pick the right ones anyway. This sets the flags I guessed based
on what other drivers used, and Peter confirmed that they are the
right ones.
