No, it doesn't, it uses "bcrmf".

This typo has spread to all ARM device trees:

$ git grep bcrmf -- arch/arm/boot/dts/
arch/arm/boot/dts/imx6sx-nitrogen6sx.dts:       brcmf: bcrmf@1 {
arch/arm/boot/dts/imx6ul-opos6ul.dtsi:  brcmf: bcrmf@1 {
arch/arm/boot/dts/sun6i-a31s-sinovoip-bpi-m2.dts:       brcmf: bcrmf@1 {
arch/arm/boot/dts/sun7i-a20-bananapi-m1-plus.dts:       brcmf: bcrmf@1 {
arch/arm/boot/dts/sun7i-a20-bananapro.dts:      brcmf: bcrmf@1 {
arch/arm/boot/dts/sun7i-a20-cubietruck.dts:     brcmf: bcrmf@1 {
arch/arm/boot/dts/sun7i-a20-i12-tvbox.dts:      brcmf: bcrmf@1 {
arch/arm/boot/dts/sun7i-a20-wits-pro-a20-dkt.dts:       brcmf: bcrmf@1 {
arch/arm/boot/dts/sun8i-h3-bananapi-m2-plus.dts:        brcmf: bcrmf@1 {

For arch/arm64/boot/dts/amlogic/* I've already fixed it, originally by
changing to "brcmf", in a second step "wifi" was requested.

Thanks for fixing this at its source.

Hopefully the maintainers in CC can make sure that at least it doesn't
spread further into new DTs.
