Before calling audio ANC ioctl functions, compare the
allocated buffer size to the size of the header and ANC cmd header
to ensure the buffer is big enough.

Develop a mechanism to faciliate the performance test for hab
and share memory.
Use "echo 0 > /sys/module/msm_hab/parameters/perf_test" to
start share memory throughput test, and use
"cat /sys/module/msm_hab/parameters/perf_test" to get the
result.

Partial Array Self-Refresh driver is used to interface
with rpm to vote/unvote on memory self-refresh from HLOS.
Driver listens to memory hotplug notifications and decides
to vote or unvote depending on memory online and offline.
This vote is considered by RPM to avoid self-refresh on
offlined DDR segments. And hence a reduce in power consumption.

Add early audio interface support to allow
synchronization between ADSP loading and early
audio playback.
Execute the command
'echo 0 > /sys/kernel/lpass_resource_mgr/check_early_audio'
to check if early audio playback is ongoing.
Output will be "Online" if early audio playback is ongoing.
