Looks like the only difference between IWD working and not working is 
when it includes the PMKID. This is due to the new PMKSA feature which 
looks like it requires some extra work on brcmfmac (using SET_PMKSA). 
Try disabling PMKSA in main.conf with:

[General].DisablePMKSA=true

This should hopefully get IWD reliably connecting.

Thanks,

James
