- Brings naming in line with existing conventions
- Replaces `_is_96Boards()` with an `any_96boards` property
- Renames `get_dt_compatible_field()` to `check_dt_compatible_value()`
to distinguish between returning a field's string value and a boolean
check on whether a value is present.
- Adds a 96Boards check to `bin/detect.py`.
This might still need some changes, and definitely needs tested on actual
96Boards hardware.
