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

Applied to topic/cs35l41 branch, which is merged to for-next (for
6.8).
