To make progress with SoundWire support, this patchset provides the
missing support for clock stop modes, and revisits all Cadence Master
register settings. The current code is for some reason not aligned
with internal documentation and hardware recommended flows,
specifically for multi-link operation.
Changes since v1:
Removed log in is_clock_stop(), use the helper in the main
clock_stop() and change return 1->return 0.
Fixed squash issue in patch5 to remove irrelevant udelay() change
Added Patch17 to clear FIFOs and avoid pop noise
