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`
```
