drm/amdgpu/gfx10: add updated GOLDEN_TSC_COUNT_UPPER/LOWER register offsets for VGH

The address of the GOLDEN_TSC_COUNT_UPPER/GOLDEN_TSC_COUNT_LOWER for

The offset of the GOLDEN_TSC_COUNT_UPPER for Vangogh is 0x0025 by
calculation.
The offset of the GOLDEN_TSC_COUNT_LOWER for Vangogh is 0x0026 by
