This change will enable firmware to perform Hierarchical
video encoding for P frames. Hierarchical video encoding is
used to improve error resilience and temporal scalability.
The encoded frames are logically organized in to multiple
layers with frames in one layer referencing only frames
from lower layers. The lowest layer, i.e. base layer, is
the only exception.

For dynamic output buffers, firmware can hold on to a
output buffer reference after releasing it to
driver. The buffer is marked as read only and sent
back to client. The driver maintains the reference
of this buffer and decrements it when firmware
sends the release reference event. The client is
notified of the release reference event.

VP8 specification does not define level or profile concept but
specify a version. The OpenMax IL version 1.1.2 specify a single
profile and multiple levels for VP8 codec, the levels are indeed the
version numbers. The way of setting the codec version using level
field comes from the definitions at OpenMax IL. Since is a single
profile, level value is use to set-up the version but FW expects the
version value to be pass in the profile field, for that reason
incoming level is copy to FW profile.

In cases the driver's frameskipping is unacceptable, provide a tuning
parameter that controls the skip frequency. fpsvariance is the
percentage for the fps that the driver can overshoot by, which allows
for the driver to skip fewer frames. fpsvariance == 0 forces the driver
to strictly observe the fps, whereas fpsvariance == 100, allows the
driver to completely ignore the fps, allowing to run in a free-running
mode.
