bcm53xx: add support basic for kernel 4.3
The files directory is now split up into the files which are needed for
every kernel version and the files only needed by kernel 4.1. The files
in files-4.1 are already merged into mainline kernel 4.3. This patch
only removed patches which were merged into mainline kernel 4.3.
