Subject: greatly smoothed out SP10 ramp, and configured defaults also fixed
 random ramp stuttering, by adding phase-reset register to hwdef (though it
 still has a brief stutter sometimes while ramping down across the channel
 boundary,  at least it always seems to be smooth while going up now)

Subject: fixed SP10 ramp flickering properly, using double-buffered registers
 instead of my janky forced phase-reset workaround (gchart found the solution
 but couldn't reproduce the issue,  so I tried his method and confirmed it
 seems to be fixed)
