Subject: [PATCH] sound/sgtl5000: fix initial setting for DAC data source

According to documentation bit 3:2 in register SSS_CTRL are
reserved and zero, so the setting of 0x0008 does not make much sense.
Instead, bit 4 should be set as is with power up, to reflect
routing of I2S_IN to DAC correctly.

Looks much like an off by one error.
