i3c: mipi-i3c-hci: Change name of INTR_STATUS bit 11

INTR_STATUS bit 11 INTR_HC_RESET_CANCEL was probably projected for the
MIPI I3C HCI specification version 2 but was not ever implemented.

This bit is first time specified in the v1.2 as HC_SEQ_CANCEL_STAT
"Host Controller Cancelled Transaction Sequence". Update the definition
and debug print of it accordingly.

While at it, change DBG() print to dev_dbg().
