drm/amdgpu: use %pad format string for dma_addr_t
DMA addresses can be shorter than u64, which results in a broken debug output:
drivers/gpu/drm/amd/amdgpu/amdgpu_gart.c: In function 'amdgpu_gart_table_ram_alloc':
drivers/gpu/drm/amd/amdgpu/amdgpu.h:41:22: error: format '%llx' expects argument of type 'long long unsigned int', but argument 4 has type 'dma_addr_t' {aka 'unsigned int'} [-Werror=format=]
drivers/gpu/drm/amd/amdgpu/amdgpu_gart.c:146:9: note: in expansion of macro 'dev_info'
146 | dev_info(adev->dev, "%s dma_addr:%llx\n", __func__, dma_addr);
Use the special %pad format string and pass the DMA address by reference.
Fixes: c9a502e981a9 ("drm/amdgpu: Allocate GART table in RAM for AMD APU")
