Subject: [PATCH v2 0/3] Support Dell models without _DSD

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.

Changes since v1:
- Rebased onto for-linus
