Subject: [PATCH 5.7 089/477] drm/nouveau: gr/gk20a: Use firmware version 0

From: Thierry Reding <treding@...dia.com>

[ Upstream commit 21454fe697fde188ad6fb541f94b9838fa73ab38 ]

Tegra firmware doesn't actually use any version numbers and passing -1
causes the existing firmware binaries not to be found. Use version 0 to
find the correct files.

Fixes: ef16dc278ec2 ("drm/nouveau/gr/gf100-: select implementation based on available FW")
