x86: move GART TLB flushing options to generic code
The GART currently implements the iommu=[no]fullflush command line parameters which influence its IO/TLB flushing strategy. This patch makes these parameters generic so that they can be used by the AMD IOMMU too. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
