drm/amd/amdgpu: Remove static from variable in RLCG Reg RW
[why]
These static variables save the RLC Scratch registers address.
When we install multiple GPUs (for example: XGMI setting) and
multiple GPUs call the function at same time. The RLC Scratch
registers address are changed each other. Then it caused
reading/writing from/to wrong GPU.
[how]
Removed the static from the variables. The variables are
on the stack.
