Adrian Hunter 91705db664 i3c: mipi-i3c-hci: Reset RING_OPERATION1 fields during init 
[ Upstream commit 78f63ae4a8 ]

The MIPI I3C HCI specification does not define reset values for
RING_OPERATION1 fields, and some controllers (e.g., Intel) do not clear
them during a software reset.  Ensure the ring pointers are explicitly
set to zero during bus initialization to avoid inconsistent state.
