cpufreq: dt: Tolerance applies on both sides of target voltage
[ Upstream commit a2022001cebd0825b96aa0f3345ea3ad44ae79d4 ] Tolerance applies on both sides of the target voltage, i.e. both min and max sides. But while checking if a voltage is supported by the regulator or not, we haven't taken care of tolerance on the lower side. Fix that.
