Move ras_hw_supported into struct amdgpu_dev.
The dependency is:
struct amdgpu_ras <== struct amdgpu_dev <== ASIC,
read as "struct amdgpu_ras depends on struct
amdgpu_dev, which depends on the hardware."
This can be loosely understood as, "if RAS is
supported, which is property of the ASIC (struct
amdgpu_dev), then we can access struct
amdgpu_ras."
v2: Fix a typo: must binary AND in ternary cond
in amdgpu_ras.c
