[Buildroot] [PATCH v1] board/raspberrypi/config*.txt: remove failing 'dtoverlay=krnbt=on'

[Peter Seiderer]

Remove failing 'dtoverlay=krnbt=on' from config.txt introduced with commit
689b9ac439 ("package/rpi-firmware: rework boot/config file handling") [1] by
changing an dtoverlay option wrongly to an extra line (instead of changing
to an proper dtparam line), but as no one complained since 2021 just
drop it (and upcoming raspberry pi kernel/device tree will enable
it by default [2]).

Fixes (on the board):

	$ cat /proc/device-tree/chosen/user-warnings
	Failed to load overlay 'krnbt=on'
