I see only one call to sdhci_init_slot in bcm2835_sdhost.c so maybe that's the problem.  It supports exactly one SDIO device, a memory card.

Oh, here is another update:
https://lists.freebsd.org/archives/freebsd-arm/2020-February/021340.html which points to https://lists.freebsd.org/pipermail/freebsd-wireless/2020-February/008985.html

So, somebody on the freebsd-wireless might know about it also,

IMHO It would be nice if the work-in-progress of this driver was shared in a known place so more people could help.

Regards,
Ronald.
