The PWR_ANLG1 reg not only contains various power on/off bits, it also contains 2 bits which select if the LDO generates 1.0, 1.1 or 1.2V. 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.
