There's actually very little going on on the apicula side, but a future nextpnr fix will split each of IOLOGICA and IOLOGICB into two directions: IOLOGIC in and IOLOGIC out. This allows us to combine two IOLOGICs at once to work with IOBUF, which addresses issue YosysHQ/nextpnr#1275 The nature of the fixes in this PR is such that it will work with the old version of nextpnr and everything that successfully passes through netxpnr will work.
