drm/gem: rename struct drm_gem_dma_object.{paddr => dma_addr}
The field paddr of struct drm_gem_dma_object holds a DMA address, which might actually be a physical address. However, depending on the platform, it can also be a bus address or a virtual address managed by an IOMMU.
Hence, rename the field to dma_addr, which is more applicable.
In order to do this renaming the following coccinelle script was used:
``` @@ struct drm_gem_dma_object *gem; @@
- gem->paddr + gem->dma_addr
@@ struct drm_gem_dma_object gem; @@
- gem.paddr + gem.dma_addr
@exists@ typedef dma_addr_t; symbol paddr; @@
dma_addr_t paddr; <... - paddr + dma_addr ...>
@@ symbol paddr; @@ dma_addr_t - paddr + dma_addr ;
```
This patch is compile-time tested with:
``` make ARCH={x86_64,arm,arm64} allyesconfig make ARCH={x86_64,arm,arm64} drivers/gpu/drm` ```

drm/aspeed: Use dt matching for default register values
There are minor differences in the values for the threshold value and the scan line size between families of ASPEED SoC. Additionally the SCU registers for the output control and scratch registers differ between families.
This adds device tree matching to parameterise these values, allowing us to add support for the AST2400 now, and in the future the AST2600.
