[Buildroot] [git commit branch/2023.08.x] board/raspberrypi: fix autoprobing of bluetooth driver

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ec866af755162efec821a61b156dc562a326804f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.08.x

The commit 689b9ac439 (package/rpi-firmware: rework boot/config file
handling) has split in two the property:

	dtoverlay=miniuart-bt,krnbt=on

Into:

	dtoverlay=miniuart-bt
	dtoverlay=krnbt=on

The initial property contained the dtbo file miniuart-bt[1] and its
parameter krnbt=on[2][3].

The first syntax is correct while the second is not. The krnbt=on is not
a dtoverlay[4] but a dtparam[5]. Therefore the property dtparam must be
used instead.

This fixes:

	# cat /sys/firmware/devicetree/base/chosen/user-warnings
	Failed to load overlay 'krnbt=on'
