ASoc: msm: qdsp6: Add ultra low latency playback support

Using ULL further reduces continuous latency when
compared to the current low latency path.
This is achieved by having no post-processing in
the DSP along with smaller buffer sizes

ASoC: msm: Fix playback failure on device switch during ULL playback

When a device switch happens for ultra low latency playback, we are
opening a regular playback COPP. ULL stream is routed to a non ULL
COPP. ULL stream can be only routed to a ULL COPP. This results in
playback failures. The fix is to use the perf mode flag as a
part of front end instead of back end dai.

ASoC: msm: qdsp6v2: Update the topology if there is no ACDB

The topology for ASM and ADM is passed down from ACDB to adsp.
If there is no ACDB, then the topology ID is zero. In the current
implementation, whenever the topolpgy ID is zero, then the default
topology is used for asm and adm. The problem arises for msm8x10
because it support only null/none topolgy. It causes audio playback
failure in factory test mode when ACDB loader is disabled by factory
test application. Update the topology to null/none from default to
cover all the platforms.

ASoC: msm: Fix playback failure with tinyalsa test app

PCM playback through tinyplay test app fails as it tries
to write data in chunks of ring buffer size instead of
period size. msm_pcm_playback_copy function checks the
available bytes in the shared buffer and rejects if the
bytes received are more.
Instead of rejecting the buffer, copy bytes equal to available
size i.e. period size. The ALSA framework will take care of
updating the offsets and looping through the remaining data.

Use 32-byte aligned buffer address to ADSP for playback

This causes failure in record and playback.
