UPSTREAM: drm/nouveau: select FW caching

[ Upstream commit 6b481ab ]

nouveau tries to load some firmware during suspend that it loaded
earlier, but with fw caching disabled it hangs suspend, so just rely on
FW cache enabling instead of working around it in the driver.

Fixes: 176fdcb ("drm/nouveau/gsp/r535: add support for booting GSP-RM")
