Currently, below code actually does not update any bit because
SGTL5000_SMALL_POP is 0.
snd_soc_update_bits(codec, SGTL5000_CHIP_REF_CTRL, SGTL5000_SMALL_POP, 1);
The SGTL5000_SMALL_POP should be BIT(0) rather than 0, fix it.

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

SGTL5000_PLL_FRAC_DIV_MASK is used to mask bits 0-10 (11 bits in total) of
register CHIP_PLL_CTRL, so fix the mask to accomodate all this bit range.

According to the datasheet:
CHIP_MIC_CTRL 0x002A
BITS[9:8] BIAS_RESISTOR
0x0 = Powerd off
0x1 = 2.0 kohm
0x2 = 4.0 kohm
0x3 = 8.0 kohm
Thus SGTL5000_BIAS_R_MASK should be defined as 0x0300 instead of 0x0200.

Remove unnecessary headers:
