Our current I2C FSM does not support disabling the host mode in a graceful way. We should cover this in case multi-host becomes supported. This issue is an icebox for a TODO in the RTL: https://github.com/lowRISC/opentitan/blob/902088b5728183d560ece930c19406b7ccb2811f/hw/ip/i2c/rtl/i2c_fsm.sv#L1299

Multi-host is currently not planned for PROD, hence leaving this in the backlog.
