msm: vidc: Set extradata flag properly

Extradata flag is not set to output buffer header's flag in
case when a Mpeg2 clip is played and extenstion and user data
extradata is not enabled.
This change fixes the issue and set extradata flag properly
if extradata is enabled and extradata is available with the
the buffer.

msm: vidc: Optimize IOMMU map size for H264 decoder

IOMMU map size is not required to be double the actual
buffer size for H264 decoder. So reducing IOMMU map
size for H264 format which will enable support for
two H264 decoder instances in parallel in smooth streamig
mode where the number of output buffers equal to 18 with
each buffer size equal to 1080p buffer size.

msm: Add support for ION Flushing without virtual address

Video has very large buffers to be flushed. Due to lack of
vmalloc space, ion_map_kernel cannot be called on each of
the video buffers. With this change the ion handle can be
flushed without the need of the kernel mapping.

ASoC: Avoid putting stream state to STOP when stream paused

When multiple Front-end are using the same Back-end, putting
the stream state for a Front-end to STOP will make the the Backend
stream to be released, when the front-end is paused. This will avoid
the Backend to be released (when another active front-end stream is
present).
Instead, put the stream state to PAUSED, which will keep the Back-end
ON.

ASoC: audio: Fix BE not disconnected even codec teardown

Scenario:
When FE1(LowLatency) comes in which opens BE1 and puts it in state
SND_SOC_DPCM_STATE_START. Similarly FE2(LPA) comes in with
connecting to same BE. Now FE2 is in SND_SOC_DPCM_STATE_PREPARE
state and waits for TRIGGER_START. Meanwhile FE1 is closed which
doesn't affect BE1 and FE2 which are connected.
Also, for FE2 pcm_close is called before TRIGGER_START itself.
In such a case, BE1 is not getting disconnected (afe_close is
not called) while Codec is teared down resulting in Slimbus
overflow.

Fix:
Whenever BE1 is found to be in SND_SOC_DPCM_STATE_START state
and FE1 being connected is not started yet, and close sequence
happens for this FE, then allow hw_free to happen for BE1 if
this is the only FE connected to this BE1. This allows BE to be
disconnected which calls afe_close then followed by Codec teardown
not resulting in any Slimbus overflows.

Advance hardware pointer by period size even if the packet

asoc: msm: Add flexible period count to pcm record driver

 In pcm recording, if buffers are not requested from dsp at real
 time then dsp drops the buffers and sends partial buffers. This
 is causing record failures. Pcm record platform driver has two
 periods. If system is loaded, read request will not be at real
 time. Add flexible period count to pcm record platform driver
 so client can configure the period count.
