i3c: mipi-i3c-hci: Add DMA ring abort/reset quirk for Intel controllers
Some Intel I3C HCI controllers cannot reliably restart a DMA ring after an
ABORT. Additional queue resets are required to recover, and must be
performed using PIO reset bits even while operating in DMA mode.
This behavior is non-standard. Introduce a controller quirk to opt into
the required PIO queue resets after a DMA ring abort, and enable it for
Intel LPSS I3C controllers.
