linux-firmware: broadcom: use symlink to provide NVRAM for some RPis 

This is to align the implementation with upstream `linux-firmware`.

Some Raspberry Pi boards do not have dedicated NVRAM in `linux-firmware`
source repository, their NVRAM is provided through a symbolic link to
NVRAM of another board with an identical wireless design.
