Subject: cpufreq: dt: Tolerance applies on both sides of target voltage

From: Viresh Kumar <viresh.kumar@linaro.org>

commit a2022001cebd0825b96aa0f3345ea3ad44ae79d4 upstream.

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.
