ARM: msm: dts: enable gpio configuration of ti amplifier 



On apq8053 hw variants gpio68 is used to power on external
ti amplifier. In current setup gpio68 is configured as part
of cdc_pdm_comp_lines which are not applicable for
apq8053 hw variants causing the gpio68 always pulled down
and not getting the ti amplifier powered on.
Configure gpio68 as part of cdc_quat_mi2s_gpios instead of
cdc_pdm_comp_lines.
