Patch: Fix N770 brf6150 bluetooth driver

[Andrew de Quincey <adq_dvb@xxxxxxxxxxxxx>]

This driver has the same problem as the cbus drivers - mismatch  
between platform_device and non-platform driver APIs.

Switching it to use platform_driver removes the random corruption and  
badness I was seeing on boot.

    Fix brf6150.c platform_device breakage
    
    This driver has the mismatch between platform_devices and non-platform drivers.
    Switch it to use platform_driver as well.
