[BUG] Setting HYBRID_THRESHOLD to 0 hangs the board at boot

[sargonphin]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

Setting HYBRID_THRESHOLD in Configuration_adv.h to 0 could potentially prevent boards from booting successfully after flashing, without permanent damage

Setting HYBRID_THRESHOLD to 0 is possible at runtime and is effectively disabling StealthChop except at full stop

Bug Timeline

New issue

Expected behavior

Setting this parameter to zero is produces the same outcome than at runtime

OR

SanityCheck.h prevents the compilation from happening

Actual behavior

Compilation is successful but the board does not boot. Flashing is still possible, activity is visible but the firmware hangs at loading

Steps to Reproduce

1. Enable HYBRID_THRESHOLD
2. Set any stepper threshold to zero
3. Compile & Load
