Stefanos Kornilios Mitsis Poiitidis 3fe8f0eb94 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
