Revert "redhat/configs: Enable genet and brcmfmac wlan"

This reverts commit 42ac45c7.

That commit was enabling not only RPi wireless driver but also the whole wireless stack for aarch64, which was previously disabled. To enable wlan on aarch64, more discussion and testing is required, so better to put it off now before beta compose and include later after more carefully review and testing.

Moreover, RH policy is to support everything we build, so it cannot be build but considered as "comunity supported", as we thought.
