Victor Zhao 9250f97fd5 drm/amd/amdgpu:save psp ring wptr to avoid attack 
[ Upstream commit 2370eba9f552eaae3d8aa1f70b8e9eec5c560f9e ]

[Why]
When some tools performing psp mailbox attack, the readback value
of register can be a random value which may break psp.

[How]
Use a psp wptr cache machanism to aovid the change made by attack.
