Hi Abdiel

I noticed that there’s no API to call `dma_set_mask/dma_set_coherent_mask`.

This should probably be included, i.e.:

```
By default, the kernel assumes that your device can address 32-bits of DMA addressing.
For a 64-bit capable device, this needs to be increased, and for a device with limitations,
it needs to be decreased.
```
