x11-drivers/nvidia-drivers: warn about the GSP default in 555

Browse Source 
Looking at NVIDIA's forums, many are hitting regressions with this
and disabling fixes them. Feels unlikely everything will be resolved
before it goes out of beta and gets keyworded (unless default is
reverted), so it may help a few users to warn.
