MMIO offsets for GFX.

This class handles MMIO reads/writes to the GFX_BASE aperture which are generally read/written by the gfx driver source here:

 drivers/gpu/drm/amd/amdgpu/amdgpu_discovery.c

https://github.com/RadeonOpenCompute/ROCK-Kernel-Driver/blob/master/ drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c

The MMIO addresses in the file are dword addresses. Here they are converted to byte addresses so gem5 does not need to shift the values.
