dev-amdgpu: Fix GART PTE size

The GART table is a legacy 1-level page table primarily used for
supervisor mode accesses to GPUs. The PTE size is 64-bits, not 32-bit.
This causes memory sizes >3GB (in X86) to fail loading amdgpu driver.

This changeset fixes the issue by setting the GART mappings to the
correct data type.
