Subject: [PATCH v2 1/2] drm/panfrost: Remove type name from internal structs

The two structs internal to struct panfrost_dump_object_header were
named, but sadly that is incompatible with C++, causing an error: "an
anonymous union may only have public non-static data members".

However nothing refers to struct pan_reg_hdr and struct pan_bomap_hdr
and there's no need to export these definitions, so lets drop them. This
fixes the C++ build error with the minimum change in userspace API.

Fixes: 730c2bf4ad39 ("drm/panfrost: Add support for devcoredump")
