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.

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.

msm: vidc: detect mbaff information from firmware

Firmware will set the FBD flags if mbaff interface

the mbaff information was parsed in the v4l2 video
client, but now firmware parses and sends the information.

msm: mdss: Reserve single SMP block for writeback mixer pipes

Writeback does not have stringent requirement for latency
buffers. So, SMP blocks reservation for the pipes attached
to writeback block can be restricted to single SMP block for
each plane. This makes more SMP block available for other
clients.

Pipes availablity for a use case can be computed taking these
values, based on which, composition decisions can be made.

msm: mdss: optimize MDP pipes cleanup

There are cases where pipe cleanup can happen without display commit.
This means that the pipe was never programmed to hardware, in these
cases the pipe can be cleaned up without the need of display commit
cycle to happen. Also there is no need to access hardware to release
resources such as SMPs since they have not been programmed yet.

msm: mdss: implement overlay prepare ioctl

Overlay prepare will allow a full frame with multiple overlays to be
configured at once and perform frame level checks before being pushed to
display. This function guarantees that if the call is successful, the
frame can be displayed successfully on the screen when display commit is
called.
