zorro: Do not allocate zorro_autocon[] statically
Currently the array of Zorro devices is allocated statically, wasting up to 4.5 KiB when running an Amiga or multi-platform kernel on a machine with no or a handful of Zorro expansion cards. Convert it to conditional dynamic memory allocation to fix this. amiga_parse_bootinfo() still needs to store some information about the detected Zorro devices, at a time even the bootmem allocator is not yet available. This is now handled using a much smaller array (typically less than 0.5 KiB), which is __initdata and thus freed later. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
