Wifi on RPi 3B+ appears to no longer work after updating kernel to 4.18.17-300.fc29.aarch64.

Worked OK with 4.18.16-300.fc29.aarch64

After update:
dmesg | grep brcm
[ 19.386730] bluetooth hci0: Direct firmware load for brcm/BCM4345C0.hcd failed with error -2
[ 19.396367] Bluetooth: hci0: BCM: Patch brcm/BCM4345C0.hcd not found

Before update:
dmesg | grep brc
[ 30.062387] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6
[ 30.075952] usbcore: registered new interface driver brcmfmac

There's been a regression here, I'm aware of it but due to travel I've
not had a chance to fully debug it. I asked one of the reporters to
file a bug so it can be tracked.
