After a bit more work I now have a wireless connection!
So I guess we now have confirmation that the driver supports the
second mmc slot even for SDIO!
I used David's appended patch plus Tony's 4 HSMMC patches.
I used version 8.73.7p3 of the Marvell SD8686 firmware and helper
binaries and placed them in /lib/firmware.
The log:
