drm/amdgpu: Add PSP fw version check for fw reserve GFX command
The fw reserved GFX command is only supported starting from PSP fw
version 0x3a0e14 and 0x3b0e0d. Older versions do not support this command.
Add a version guard to ensure the command is only used when the running
PSP fw meets the minimum version requirement.
This ensures backward compatibility and safe operation across fw
revisions.
