[PATCH v3] ASoC: rt1011: Fix 'I2S Reference' enum control caused error

Access to 'I2S Reference' enum causes alsamixer to fail to load:
$ alsamixer
cannot load mixer controls: Invalid argument

cml_rt1011_rt5682 cml_rt1011_rt5682: control 2:0:0:TL I2S Reference:0: access overflow

The reason is that the original patch adding the code was using
ucontrol->value.integer.value[0]
instead the correct
ucontrol->value.enumerated.item[0]

for an ENUM control.

Fixes: 87f40af26c262 ("ASoC: rt1011: add i2s reference control for rt1011")

Hi,

Changes since v2:

Peter
