Note there is a separate on/off bit for the LDO. rt5651_set_bias_level(BIAS_OFF) used to unconditionally clear the entire register, when jack-detection support was introduced a special case for jack-detect was added which hard-codes a register value to keep the LDO voltage at 1.2 volt. This commit removes the jack-detect special case, instead simply always leaving the LDO voltage control bits as is on BIAS_OFF.
