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
7e7a43c32a
("PCI: don't export device IDs to
userspace") before, so it was also forgotten.
Split off and export the Zorro definitions used by bootstraps.
