ASoC: stac9766: fix wrong usage of DECLARE_TLV_DB_LINEAR() As long as reading datasheet of STAC9766/9767, this driver includes wrong usage of DECLARE_TLV_DB_LINEAR(). In "8.1.2. Master Volume Registers", attenuation of lineout volumes is represented in 5 bits by -1.5 dB/step from 0 to -46.5 dB. Thus, 'master_tlv' should be dB step representation. In "8.1.14. Record Gain", gain of volumes is represented in 4 bits by 1.5 dB/step from 0 to 22.5 dB. Thus, 'record_tlv' should be dB step representation. In "8.1.5. PC BEEP Volume", attenuation of volume is represented in 4 bits by -3 dB/step from 0 to 45 dB. Thus, 'beep_tlv' should be dB step representation. In "8.1.7. Stereo or Mic Volume" and so on, gain of volumes is represented in 5 bits by -1.5 dB from 12 to -34.5 dB. Thus, 'mix_tlv' should be dB step representation. Totally, current implementation includes misuse of TLV-related macro. This commit replaces usage of DECLARE_TLV_DB_LINEAR() with SNDRV_CTL_TLVD_DECLARE_DB_SCALE(), to give proper information to applications in user land.
