ALSA: hda: tas2781: fix tas2563 EFI data endianness

Before conversion to unify the calibration data management, the
tas2563_apply_calib() function performed the big endian conversion and
wrote the calibration data to the device. The writing is now done by the
common tasdev_load_calibrated_data() function, but without conversion.

Put the values into the calibration data buffer with the expected
endianness.
