Subject: [PATCH 4.19 040/168] drm/radeon: disable AGP by default

From: Christian König <christian.koenig@....com>

[ Upstream commit ba806f98f868ce107aa9c453fef751de9980e4af ]

Always use the PCI GART instead. We just have to many cases
where AGP still causes problems. This means a performance
regression for some GPUs, but also a bug fix for some others.
