ecp5: Proof-of-concept using IdStringList for bel names
This uses the new IdStringList API to store bel names for the ECP5. Note
that other arches and the GUI do not yet build with this
proof-of-concept patch.
getBelByName still uses the old implementation and could be more
efficiently implemented with further development.
