ASoC: sgtl5000: Fix SMALL_POP bit definition

Browse source 
commit c251ea7bd7a04f1f2575467e0de76e803cf59149 upstream.

On a mx28evk with a sgtl5000 codec we notice a loud 'click' sound  to happen
5 seconds after the end of a playback.

The SMALL_POP bit should fix this, but its definition is incorrect:
according to the sgtl5000 manual it is bit 0 of CHIP_REF_CTRL register, not
bit 1.

Fix the definition accordingly and enable the bit as intended per the code
comment.

After applying this change, no loud 'click' sound is heard after playback
