ASoC: sgtl5000: Write all default registers
If an error occurs writing defaults, produce an error message but continue writing other registers. The failure of a single write should not cause catastrophic device failure. In at least one occurrence, I2C writes of CHIP_ANA_POWER were nacked, though continuing allowed the device to operate properly.
