The mismatch_mask in match_region() is set but never actually
being used. So remove it as Clang complains.

This introduces bit arrays as a new data type. This is different
than sys_bitfield as it is working on raw arrays of 32-bit
data. The bit arrays encode additional data inside the struct
to avoid going beyond the declared number of bits, and also
provides locking.
