tmu: Correctly schedule next interrupt in underflow, correctly differentiate between large values and underflows
...
- 32 bit code was "fudgy" on this, so simplified via 64bit counters for edge detection
- Maths to count cycles were wrong
- Let's not do 32 bit wrapped maths after beers without any kind of pen-and-paper design
Should fix #594 , also see #645
