drm/amdgpu: handle PCIe root ports with addressing limitations
amdgpu uses a need_dma32 flag to indicate to the drm core that some
allocations need to be done using GFP_DMA32, but it only checks the
device addressing capabilities to make that decision. Unfortunately
PCIe root ports that have limited addressing exist as well. Use the
dma_addressing_limited instead to also take those into account.
