Subject: drm/nouveau: fix out-of-tree module build
Git-commit: bbd540c072a8f7ad7aa4ba6a67ad5b30322e188b
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

The $(srctree) addition a while back busted building the out-of-tree
version of the module, and I've been hacking it up ever since.

This allows us to work around the issue.
