ALSA: cs35l56: Apply calibration from EFI

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

Factory calibration of the speakers stores the calibration information
into an EFI variable.

This set of patches adds support for applying speaker calibration
data from that EFI variable.

The HDA patch (#5) depends on the ASoC patches #2 and #3
