ASoC: msm: qdsp6v2: Remove cmd_state from ASM header function

Cmd_state indicates whether the callback has been received
and whether the function should exit wait.
Remove setting of this variable in ASM header because
some functions such as get_session_time need ASM header
but do not need to modify this flag.

ASoC: msm: qdsp6v2: Add a new waitqueue state for mem map/unmap

All of the commands being sent to the DSP are using cmd_state flag
which can be overwritten when several commands are sent at the same
time. This results in Memory map command timing out. The change will
separate the memory flag from flags for other commands so that they
do not overwrite each other.

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.

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.

mdss_iommu_attach/mdss_iommu_dettach can happen in

msm: mdss: Reset pipe's mfd parameter during pipe free

There is a corner case with dma pipe. If its set call
fails as line mode (for mdp) and is configured
subsequently as block mode (for rotation), mfd parameter
of the dma pipe structure does not get reset during set
failure cleanup. This causes unnecessary force dma
cleanup call in rotatorp lay which gets hang and
results in rotator fence timeout.
