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.

+Subject: [PATCH RFC] bcma: use two different initcalls if built-in
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This is needed as we can't initialize bus during fs_initcall.
+Initialization requires SPROM which depends on NVRAM which depends on
+mtd. Since mtd, spi, nand, spi-nor use standard module_init, we have to
+do the same in bcma.
+Without this we'll try to initialize SPROM without having a ready SPROM
+proviver registered using bcma_arch_register_fallback_sprom.

+---
+While this patch seems to work and I can compile bcma as built-in and
+module, I'm not too proud of it. I don't really like these #if(n)def
+tricks and I'm afraid bcma_modinit may be called even if
+bcma_modinit_early failed.
+
+Do you see any better idea of solving this?
