Discussed during triage meeting. We have sufficient coverage for passthrough in other places. We are not expecting any RTL changes to result from the DV fix expected in this issue, so we are comfortable moving this to M5.

This test also has 100% pass rate with Xcellium, which is the sign-off tool for spi_host.

Moving to Earlgrey-PROD.M7 as we are using Xcellium for spi_host block level sign-off.
