crda: add regdb_dfs_regions

These are already in dbparse.py. As it stands silicon
vendor DFS solutions group up DFS compliance requirements
into three categorical groups. Each country that requires
DFS has opted to follow one type of group category set
of rules.

CRDA was already reading the DFS regions but using
nl80211.h definitions for its parsing and printing of
these flags, its best to use our own OS agnostic
definitions.
