x86 gart: reimplement IOMMU_LEAK feature by using DMA_API_DEBUG
IOMMU_LEAK, GART's own feature, dumps the used IOMMU entries when
IOMMU entries is full, which might be useful to find a bad driver that
eats IOMMU entries.
DMA_API_DEBUG provides the similar feature, debug_dma_dump_mappings,
and it's better than GART's IOMMU_LEAK feature. GART's IOMMU_LEAK
feature doesn't say who uses IOMMU entries so it's hard to find a bad
driver.
This patch reimplements the GART's IOMMU_LEAK feature by using
DMA_API_DEBUG.
