brcmfmac: replace dongle command list with .preinit() callback

The bus-specific interface allowed a list of dongle commands to be
provided to the common driver part. However, upcoming functionality
requires a more dynamic behaviour. Hence the list is replaced
by a new callback function so the bus-specific driver part can
implement this behaviour.
