To avoid changing the visibiliy of data types when including
hook definition headers remove header file inclusions from
the hook definition header files.
Instead, the hook definition headers should just have forward
declarations that don't require full definition.
To provide full definitions of the types for the KMI, the
headers that define the types should be included by the
source file that instantiates the hooks - normally
vendor_hooks.c.
Since the KMI is frozen, some of the inclusions are still
required to preserve the CRC associated with symbols. Keep
these inclusions under #ifdef __GENKSYMS__.

android_vh_audio_usb_offload_suspend:
To skip pcm suspend in offload mode
We need a vendor hook to skip usb audio suspend in offload mode.
In kernel5.4 the cmd SNDRV_PCM_TRIGGER_SUSPEND and SNDRV_PCM_TRIGGER_STOP are treated differently.
However, they are treated the same in kernel5.15, which will lead to system suspend while music playing in offload mode.

Add vendor hooks to capture when a USB audio interface is probed
and disconnected. These will allow for supporting offloading of
audio device handling to a co-processor.
The disconnect hook needs to be restricted as the additional
vendor handling may need to perform operations (such as
wait_for_completion) in non-atomic context.
