compat-drivers: add UAPI backport fixes

The patch was posted for inclusion upstream. The
DRM code uses some include headers and if we are
not specific about the path what ends up happening
is our old kernel header files gets used instead of
the new UAPI header files.

For details on the UAPI changes:

+Subject: [PATCH 1/2] uapi: update includes for drm content when no kernel API
+ exists
+
+The UAPI changes split kernel API and userspace API
+content onto two separate header files. The userspace
+API drm content was moved to include/uapi/drm/ with the
+same file name while kernel specific API content was
+kept under include/drm/ with the same file name. When
+one file was split into two files the kernel header
+includes the uapi header and a UAPI prefix was added to
+the uapi header for its header guard. When there was no
+kernel API content found the uapi header file was the
+only one that was kept and the original guard for the
+header file was kept. In this particular case the
+original users of this header file were not modified
+and the uapi header file is expected to be picked up
+by path.
+
+This may work well at compilation on the kernel but when
+backporting this creates a few complexities. To help with
+backporting [0] lets be explicit about the new uapi path
+when there is no respective kernel API header file. For
+more details on the UAPI changes see the lwn article on
+this [1].
