Revert "OMAP3630+: SmartReflex 1p5: remove voltage clamp down"

This reverts commit afadff82e7b2041498c95f266b76b21dda04e703.
SR15: skip calibration on notrim freqs
SR1.5: just to complete the calibration tweak for high freq/voltage
Custom SR Tuning V2: allow SR to calibrate high voltages

For MPU only, should have zero effect on IVA and CORE
