i want to play safe. Could you please check the Rev of your 3 B board? You can find it on the upside of the PCB below the GPIO pin header (e.g. i have Rev 1.2).

Btw the intention of this patch was to enable Wifi. Could you please provide a complete dmesg in case wlan0 is absent?

Interesting SDHCI and BRCMFMAC are compiled as a module. Maybe this causes the issue. I tested today 4.20rc-1 with arm64/defconfig and wlan0 is always there. Could you please change your config to:
CONFIG_MMC_SDHCI_IPROC=y
and on the other side i will test your config.
