> 
> New generation Intel controllers(N) need to support RF from (N-1)
> generation. Since PID comes from OTP present in RF module,
> *setup* function gets mapped to BTUSB_INTEL_NEW instead of
> BTUSB_INTEL_NEWGEN. This patch converges INTEL_NEW and
> INTEL_NEWGEN mappings and defines a new generic *setup* function. All
> the required information to load the correct driver is read from controller in
> generic *setup* and branchs out appropriately.
