We shouldn't need to call venus_hfi_set_ocmem if the allocation of ocmem
failed.

the frame level QP.

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: Query the core on VIDIOC_G_FMT

Previously we only queried the core for buffer requirements in
VIDIOC_REQBUFS, and relied on that information in _G_FMT.  However,
there's no expectation that the client calls _REQBUFS before _G_FMT,
which leads to stale information being returned as part of _G_FMT.

As such, always retreive fresh info from the core for either ioctl.
