QP range differs from codec to codec. This change adds support
for VP8 QP min and max range.

msm: vidc: Add support to request frame level QP information

The resulting QP information for H264 is the slice level
QP averaged over whole frame; for all other codecs its
frame level QP.

[media] v4l2: Add enums to request frame bits info as extra-data

This option is intended to be used to request as extra-data
the size in bits from frame header and frame itself.

msm: vidc: Add support to request frame bits info as extra-data

Provides information regarding number of bits in the frame (i.e frame
size expressed in bits) & also the number of bits in frame header (i.e
frame header size expressed in bits).
Number of bits in header is reported as:
For H264, sum of all slice headers bits for all the slices in the frame.
For all other codecs, number of bits in the frame header.

msm: vidc: add control to enable Hierarchical P num layers

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.

msm: vidc: Check if buffers are mapped before validating buffer_info

When buffers are not mapped by the driver (i.e. buffer being used by
kernel client), inst->registered_buffers is usually empty.  As a result,
in *_dqbuf(), binfo is always NULL.  This commit bypasses the NULL check
if buffers aren't being mapped by the driver.

msm: vidc: Free smem client after moving core to UNINIT

If userspace crashes prematurely, there will be a good chance that the
driver hasn't unmapped or freed certain buffers.  These buffers will be
freed in the state transition to UNINIT.  At that point the smem client
needs to be valid for the free/unmaps to be valid.

msm: vidc: initialize venus hfi locks during hfi creation

Venus hfi locks were initialized during core init,
which is invoked when the first video instance is
created. If a debugfs command is executed before
starting the first video instance, then video driver
crashes trying to lock an uninitialized mutex.
