msm: vidc: do not send release buffer to f/w in dynamic buffer mode

In dynamic buffer mode, the output buffers are not registered
with the firmware. So the v4l2 video driver does not need
to send release buffer command for output buffers to firmware.

msm: vidc: eliminate race condition in dynamic buffer mode

Function get_same_fd_buffer returned a pointer to
registered buffer, which shared the same fd as the
current buffer being mapped. While this buffer was
being accessed in map_and_register_buf(), it was
not guarded by the inst lock. So if the buffer was
erroneously freed, while it's still being accessed
in map_and_register_buf(), we may see a kernel
panic due to garbage values. To avoid this race
condition, introduce more checks in get_same_fd_buffer()
and return only the required handle information back to
map_and_register_buf.

Revert "msm: vidc: Disable clock gating for 8x26"

This reverts commit 4a73878e8eef36c661b99afa19122632ccffa084.
Inter frame clock gating was earlier disabled to resolve PDT
issues.Venus clock was getting disabled, when the ARM9 was
still doing bus access.
The final fix is merged as 0435d4a997f43ec1612a796ed871dbc71ae98368.
With the fix, clock gating can be enabled again to save power
during Interframe clock gating as well as during power
collapse.Hence the revert to enable Interframe clock
gating.

msm: vidc: Increase maximum buffer count limit

Some clients want to allocate more buffers on decoder
input port than required (mainly for performance reasons).
Video decoder should honor the client request as long as
V4L2 framework permits.

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

Provides information regarding number of bits in the frame (i.e frame

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.

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.

in *_dqbuf(), binfo is always NULL.  This commit bypasses the NULL check
if buffers aren't being mapped by the driver.
