The sizes of the MFC reserved memory regions for CMA are 16 MiB for the
left bank and 8 MiB for the right bank. But this isn't enough to decode
high resolution videos so increase the size for the left bank to 36 MiB
which is enough for 1080p (1920x1080).

defined.

Generic reserved memory regions bindings allow to automatically allocate
region of given parameters (alignment and size), so use this feature
instead of the hardcoded values, which had no dependency on the real
hardware. This patch also increases "left" region from 8MiB to 16MiB to
make the codec really usable with nowadays steams (with 8MiB reserved
region it was not even possible to decode 480p H264 video).
