ASoC: SDCA: Add regmap helpers for parsing for DisCo Constant values
Add helpers to parse the DisCo Constant values from ACPI and populate an
array of reg_defaults with these. This will allow drivers to access
these ACPI specified values through the same interface as other
registers that are physically present on the device, using the regmap
cache.
