The amdgpu driver needs up to 5 seconds to initialize / boot some AMD GPUs, which makes our 5 second timeout much too close to the actual needed time, leading to systems where sometimes the boot is fine and the next boot we fallback to a text based splash because we won the race from the GPU probe code.
This commit bumps the default DeviceTimeout to 8 seconds giving us a decent marging here without making it overly long.
