unprivileged process given a pcid handle for the target device.

drivers/graphics/ihdgd: Implement support for mapping memory to the GPU
...
This is done by adding entries to the global GTT page table. At startup
it only contains entries for a small chunk of memory reserved for the
GPU. This small chunk is rarely enough to contain all framebuffers we
need to allocate.

drivers/graphics/ihdgd: Introduce GpuBuffer
...
Unlike DeviceFb a GpuBuffer only has a size, not a width, height and
stride. In the future GpuBuffer can be used for dumb buffers as well as
any other kind of memory we may need to allocate on the gpu.
