Log info instead of error

[lucylq]

Fix failing jobs caused by error logging from #12295

Test failures: https://hud.pytorch.org/pr/pytorch/executorch/12631#46239138027

Note: logging errors doesn't cause an abort in the et runtime; seems like the arm test is being extra careful and parsing the log script for errors, which is causing this failure.

executorch/backends/arm/scripts/run_fvp.sh

Lines 111 to 117 in aab8021

	echo "Checking for problems in log:"
	! grep -E "^(F|E|\\[critical\\]|Hard fault.|Info: Simulation is stopping. Reason: CPU time has been exceeded.).*$" ${log_file}
	if [ $? != 0 ]; then
	echo "Found ERROR"
	rm "${log_file}"
	exit 1
	fi

So is our plan to keep this functional for a while more and then delete it?
Else we shouldn't merge this, if we really want to deprecate.

[lucylq]

Yeah - it's currently deprecated AoT (since ET beta) so we should deprecate it in the runtime. There are a bunch of tests/users with older PTEs, and they will fail if this branch is removed now.

[digantdesai]

But if the older PTEs are outside of the BC window, then we should perhaps start nudging people to update their PRs. This is one way, pinging them with a deadline is another :p
