ASoC: cs35l56: More support for new Dell laptops

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:

Some new Dell models use spare pins on the amp as a binary integer
value to indicate the speaker type. The driver must use this to
select the correct firmware files for the hardware.

Patch #1 is the new support.
The other patches are for KUnit testing.
