regulator: rk808: fix LDO range on RK806regulator-fix-v6.8-rc7for-6.8
The linear ranges aren't really matching what they should be. Indeed,
the range is inclusive of the min value, so it makes sense the previous
range does NOT include the max step value representing the min value of
the range in question.
Since 3.4V is represented by the decimal value 232, the previous range
max step value should be 231 and not 232.
No expected change in behavior since 3.4V was mapped with step 232 from
the first range but is now mapped with step 232 from the second range.
While at it, remove the incorrect comment from the second range.
