ASoC: cs35l56: Handle vendor-specific UEFI

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

This series adds handling for vendor-specific UEFI variables from Lenovo
and HP. These vendors will switch to using their UEFI variables instead
of the normal Cirrus Logic-defined mechanisms.

The model of speaker fitted (Speaker ID) is normally signaled by a GPIO,
and the driver is given access to this GPIO. Lenovo and HP will both stop
giving the driver access to the GPIO and instead the BIOS will create a
UEFI variable giving the value of the GPIO.

HP will also start using their own UEFI variable to store amp calibration
data. The content of the variable is the same as the Cirrus Logic variable,
only the UEFI name and GUID are changed.

Change in v2:
Removed unused target_uid variable and code that set it in patch 6.
