soundwire: intel: Add awareness of ACE3+ microphone privacy
ACE3 introduced microphone privacy and along this feature it adds a new
register in vendor specific SHIM to control and status reporting.
The control of mic privacy via the SHIM register is only to enable the
interrupt generation via soundwire, but not handled by the soundwire code
as the mic privacy is not a feature of the soundwire IP.
On the other hand, printing the register value brings value for debugging,
so add a new flag to allow this conditionally.
