i3c: mipi-i3c-hci: Add DMA ring abort quirk for Intel controllers
DMA rings can be aborted either per-ring via RING_CONTROL or globally
via HC_CONTROL_ABORT. The driver currently relies on the per-ring
mechanism.
Some Intel I3C HCI controllers require HC_CONTROL_ABORT to be asserted
before a DMA ring abort is effective. This behavior is non-standard.
Introduce a controller quirk to select the required abort method and
enable it for Intel LPSS I3C controllers.
