x86/gart: Disable GART explicitly before initialization
commit 4b83873d3da0704987cb116833818ed96214ee29 upstream.
If we boot into a crash-kernel the gart might still be
enabled and its caches might be dirty. This can result in
undefined behavior later. Fix it by explicitly disabling the
gart hardware before initialization and flushing the caches
after enablement.
