Add Quirks and driver properties for Dell models. Driver properties are required since these models do not have _DSD. Additionally, some laptops, including some of these, have an issue with their BIOS which causes the SPI speed to be set too slow. To ensure a decent performance for laptops with this slow speed, disable firmware loading. Running without firmware results in lower volume.
