        Disable the SW workaround for LDO bug.

        Disable the SW workaround for nPM1300 anomaly #38.

        When nPM1300 is in ULP mode, LDO is supplied from VSYS and

        then LDO is enabled, it can take long time until the LDO

        output has reached its target voltage. To avoid this, an i2c

        read is performed shortly after an LDO is enabled.

        See nPM1300 Errata manual for more details.
