Banajit Goswami 06183689db soc: add support for SND event framework
Add support for SND event framework for helping with
notifications among different audio modules/drivers.
The SND event framework functions with a master/client
mechanism, where each client and the master register
with the framework, and then notifies its own status
(UP/DOWN). Each master will share a list of clients it
is interested in, and once all the clients are registered
and notified UP, the framework's state will be UP. On the
other hand, as and when any one of the client, or the master
reports its state as DOWN while the framework is UP, the
framework state would be changed to DOWN, and all clients
and the master would be let know about the change.

# As per target team, build is done as follows:
# Defconfig : build with default flags
# Slub : defconfig + CONFIG_SLUB_DEBUG := y +
# CONFIG_SLUB_DEBUG_ON := y + CONFIG_PAGE_POISONING := y
# Perf : Using appropriate msmXXXX-perf_defconfig
#
# Shipment builds (user variants) should not have any debug feature
# enabled. This is identified using 'TARGET_BUILD_VARIANT'. Slub builds
# are identified using the CONFIG_SLUB_DEBUG_ON configuration. Since
# there is no other way to identify defconfig builds, QTI internal
# representation of perf builds (identified using the string 'perf'),
# is used to identify if the build is a slub or defconfig one. This
# way no critical debug feature will be enabled for perf and shipment
# builds. Other OEMs are also protected using the TARGET_BUILD_VARIANT
# config.
