Thanks for diving in there and suggesting a patch! I've rebuilt with
the patch but it appears dwiic fails to configure the devices:

[     1.052303] dwiic0 at pci0 dev 21 function 0autoconfiguration error: : can't map register space
[     1.052303] dwiic1 at pci0 dev 21 function 1autoconfiguration error: : can't map register space
[     1.052303] dwiic2 at pci0 dev 21 function 3autoconfiguration error: : can't map register space

No further mention of dwiic beyond that.
