board/*/linux_defconfig: panic on lockups and hung tasks

Browse Source 
Turn on OOPS-to-panic, soft/hard lockup panic, hung-task panic, and
extra workqueue watchdog reporting. This makes latent stalls visible
instead of silently freezing, improving diagnosis of issues like the
recent resource-pressure lockup.
