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

Glink may receive ssr reset event before audio has received.
Handle the ssr return code from glink as ssr reset event
at apr.

Make sure to get apr handle before sending a packet
so that it does not end up with no handle to send
the apr packet.

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.

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.

Add qcom,subsys-name for apr driver. Based on the property,
registration of notifier is done for the right co-processor,
from which notification needs to be received.

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.
