i3c: mipi-i3c-hci: Set ring start request together with enable
Set ring start request together with ring enable in hci_dma_init(). This
causes the ring abort request in hci_dma_dequeue_xfer() will raise the
INTR_RING_OP (RING_OP_STAT in MIPI I3C HCI specification) interrupt in
the RH_INTR_STATUS register.
