[dv/alert_handler] fix ping_corner_cases to adapte different ping timers In previous ping_corner_cases test, after a ping request is detected, the sequence will randomly choose to insert alert or reset. Then it will wait until the escalation phases are done. However, the new entropy LFSR SEED changes the ping frequency - that some pings are triggered in a short interval. So there are cases that ping triggered during `run_ping_interrupt_seqs`. To avoid this, this PR: 1). Remove the wait for escalation phases done logic in `run_ping_interrupt_seqs` task 2). Remove the `alert_handler_init` calls in each transaction in ping_corner_cases, it only calls `alert_handler_init` after dut_init. 3). Fix a small logic in `alert_handler_sanity` test, the set_config_locked logic should happen right after the `lock_config` call. Current logic it happened after driving alert and escalation response.

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
