Masahiro Yamada ab11a9270a drm/i915: make more headers self-contained
The headers in the gem/selftests/, gt/selftests, gvt/, selftests/
directories have never been compile-tested, but it would be possible
to make them self-contained.

This commit only addresses missing <linux/types.h> and forward
struct declarations.
