ARM: dts: qcom: reduce PM8008J LDO min voltages for Lahaina

Reduce the minimum allowed voltage for PM8008J LDO 3, 4, and 7 so
that the new minimum voltage + the dropout voltage is less than
or equal do the minimum allowed voltage of each LDO's supply
regulator.  This ensures that the supply regulators can be scaled
down to their own minimum voltage when the PM8008J LDOs are not
in use.
