ASoC: cs35l56: Add helper functions for amp calibration
Adds some helper functions and data for applying amp calibration. 1. cs35l56_read_silicon_uid() to get the silicon ID that is used to search for the correct calibration data entry. 2. Add the registers for the silicon ID to the readable registers. 3. cs35l56_get_calibration() wrapper around cs_amp_get_efi_calibration_data() 4. cs35l56_calibration_controls() table of the firmware controls for calibration data. 5. Added members to struct cs35l56_base to store the calibration data.
