[dv/lc_ctrl] use escalation agent

[cindychip]

Description

• [ ] In https://cs.opensource.google/opentitan/opentitan/+/master:hw/ip/lc_ctrl/dv/env/seq_lib/lc_ctrl_errors_vseq.sv lc_ctrl_errors_vseq.sv currently manually drive escalation input. For future release, it can enhance the esc_agent and use the agent to drive.

• [ ] In tb.sv: https://cs.opensource.google/opentitan/opentitan/+/master:hw/ip/lc_ctrl/dv/tb.sv;l=108 Add a separate clock and reset for the kmac interface. This is listed for future release because the current chip-level test already tested in a different clock and reset domain.

This sounds like a good idea (at some point...), but I don't believe it's urgently needed for M5. Tagging as a triage issue.

Moving to M7, which targets V3.

Moving to next Earlgrey release as we won't be able to complete this work as part of M7.
