Reset your NVRAM, and if you've installed some TRIM enabler software, uninstall that.
Your boot args indicates you installed something that disabled kext signing. I would imagine that software is incompatible with Sierra and is causing the panic.
After resetting NVRAM, you may be able to boot into Safe Mode as BobHarris suggested where you may be able to uninstall the software.
