feat(device_config): extend conditions to match bitfields

When a condition references a bitfield, perform bitwise matching rather than
insisting on an exact match.

This makes it easier to use feature flags packed into bitfields in conditions.

Simplify logic by refactoring repeated fetching of cond.get("dps_val")
