Add tolerance for OCP trip level

[prasimix]

We have the following problem: if OCP is enabled (i.e. e-fuse feature), it is possible that it will never trip because of tiny difference between I_SET and I_MON despite the fact that channel is calibrated. That difference could be a result of rounding and e.g. for I_SET of 2 A, a I_MON of 1.9995 mA will be measured and protection will never trip which could be fatal in some cases.

• DCP: To avoid this potential problem in case when OCP is enabled we can use 0.1% lower trip level then I_SET or difference of e.g. min 0.5 mA on high range and min 5 uA on low range.
• DCM: Lower trip level to 90% or min. 100 mA.
• DCP: Change text Trip level = Iset to Trip level = 99.9% of Iset
• DCM: Change text Trip level = Iset to Trip level = 90% of Iset
