net: wireless: bcm4329: set reference to physical device

Set the parent field of the netdevice, which causes sysfs
to create a device subdirectory under the netdevice.  Without
this subdirectory the user-space NetworkManager cannot manage
the network device.

Implemented using void * to maintain current driver implementation
of segregated OS-specific implementation.
