ASoC: sgtl5000: Fix SMALL_POP bit definition
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
