i3c: mipi-i3c-hci: Add DMA-mode recovery for internal controller errors
Handle internal I3C HCI errors when operating in DMA mode by adding a
simple recovery mechanism.
On detection of an internal controller error, mark recovery as needed and
attempt to restore operation by performing a software reset followed by
state restore. To keep recovery straightforward on this unlikely error
path, all currently queued transfers are terminated and completed with an
error.
This allows the controller to resume operation after internal failures
rather than remaining permanently stuck.
Note, internal errors indicated by INTR_HC_INTERNAL_ERR, cause the
controller to stop.
