ASoC: cs35l56: Add calibration command to store into UEFI
Add a new command 'store_uefi' to the calibrate debugfs file.
Writing this command will call cs_amp_set_efi_calibration_data()
to save the new data into a UEFI variable. This is intended to
be used after a successful factory calibration.
On systems without UEFI the write to the debugfs file will
return an error.
