CLKSTOP is defined only at the Function Group only (not at the widget level) and indicates that the Func-
tion Group and all widgets under it support D3 operation even when there is no BitCLK present on the
Link. The maximum exit time back to fully functional is 10 milliseconds from the time that the clock begins
operation and a codec address cycle has been completed. The CLKSTOP capability extends the required
functionality for D3 support while the link is operational to include:
Clock is not running (controller low power state) or is currently in a Link Reset condition.
