Exposure of driver bind/unbind to userspace via sysfs may
lead to unexpected behavior.
Hide bind and unbind by driver attribute.

Add support for virtualized APR frontend driver for audio.
Virtualized APR frontend driver resides in guest VM and
supports all legacy APR APIs. It will rely on MSM_HAB
to communicate with APR backend driver, which resides in
physical VM, where legacy SMD is utilized for communication
between APPS and ADSP.

Replace all kernel make export <all variables> instances with
export of specific variables. Depending on existing build
environment, exporting all as environment variables and
interaction with existing environment variable expansions
can lead to undefined behavior.
TODO: This change is restricted to kona flow to narrow impact.
All remaining export <all variables> need to be evaluated and
fixed similarly via subsequent changes.

In SSR/PDR, return ENETRESET errno to
propagate this failure to userspace. After
audio HAL receives ENETRESET, it stops retry
for pcm_open continuously. Rate limit the logs
when apr send packet fails during PDR/SSR
usecases to avoid watchdog timeouts.

There seems to be a delay in processing WDSP open commands
on APPS side. Sometimes it is taking more than 1 second,
results error in wdsp channels initialization. Increase the
timeout value to avoid channel connect failures.

Since apr reset is scheduled in a workqueue, it is possible that before
completion of previous session apr_deregister(), new session of apr_register()
can happen in ssr scenario. Some of the variables are not reset properly
due to this race condition. Fix this issue by failing apr_register() till
apr_deregister() is completed.

Change APR driver to platform driver and add any child
device only after ADSP up notification is received.
The idea is to have machine driver as a child device
under APR, and add the platform device for machine
driver only after ADSP is up. This will help invoke
audio drivers waiting with deferred probe and eventually
should help sound card registers successfully.
