compat-wireless/backports now contains a bcm47xx_nvram.h file to backport some of the functions in it which are used by the bcmfmac driver. This file just checks for the kernel versions and provide an empty implementations on older kernel versions. This is OK on most systems, but on bcm47xx / bcm53xx systems we want to call the real functions here. This commit removes the file from backports in our build process like we do it with the bcma and ssb header files. Instead we add a recent version into our kernel so all code uses only one header file. On bcm47xx / bcm53xx the real implementations of this code will be used.
