[Buildroot] [PATCH 2/2] configs/warp7: Improve Wifi instructions

[Fabio Estevam]

The "modprobe brcmfmac" command is not necessary because this driver
is automatically loaded.

Remove the "iwconfig" line as it is considered deprecated:

warning: `iwconfig' uses wireless extensions which will stop working for Wi-Fi 7 hardware; use nl80211

Remove the "-Dwext" parameter as it is not supported by the default kernel
configuration:

wlan0: Unsupported driver 'wext'

Tested Wifi by following the updated commands.

Series applied to master, thanks.

For info, I added a missing BR2_TARGET_UBOOT_NEEDS_GNUTLS=y
(build was failing in the docker image).

As followup maintenance patches, could you also add
custom hashes (i.e. add BR2_DOWNLOAD_FORCE_CHECK_HASHES=y and
remove the .checkpackageignore entry). See for example commit [1].

Also, there was a decision last year to move defconfigs toward using
Bootlin external toolchains. See [2]. To make sure this compiler
change will not prevent the board to boot, a test with an actual
board is preferable. Doing so while updating defconfig kernel/uboot
is a good time to do so. See for example commit [3].

Best regards,

Julien.
