drm/amdgpu: Remove volatile from CSB functions
The CSB buffer manipulation occurs in memory where the BO is mapped during initialization, and some references to this buffer are handled with volatile, which is incorrect in this scenario. There are a few cases where the use of volatile is accepted, but none of them align with CSB operations. Therefore, this commit removes all the volatile variables associated with the CSB code.
