add Dell T5400 systems to the reboot=bios automatic quirks table

Thanks for the report.

The attached patch is against the latest upstream kernel, it adds your system to the reboot quirks table. It will be committed to Linus's upstream -git kernel in a few days, and then backported to stable releases as well.
