zorro/UAPI: Disintegrate include/linux/zorro*.h
The Zorro definitions and device IDs are used by bootstraps, hence they should be exported through UAPI. Unfortunately zorro.h was never marked for export when headers_install was introduced, so it was forgotten during the big UAPI disintegration. In addition, the removal of zorro_ids.h had been sneaked into commit 7e7a43c32a8970ea2bfc3d1af353dcb1a9237769 ("PCI: don't export device IDs to userspace") before, so it was also forgotten. Split off and export the Zorro definitions used by bootstraps. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
