ASoC: max9867: don't use regmap defaults
MAX9867 codec doesn't have reset pin, so the registers don't have default values in the case of reboot without powering off. Remove the reg_defaults struct and let the regmap read initial state of the registers at startup instead of taking them from reg_defaults struct.
