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:
