drm/amdgpu: correct discovery_tmr_size init val
The legacy way to initialize discovery_tmr_size is using DISCOVERY_TMR_SIZE, while after we reduce DISCOVERY_TMR_SIZE from 64KB to 4KB, variable discovery_tmr_size is also reduced to 4KB, this is not correct, it still should be 64KB, discovery_tmr_size will be used to calculate ip_discovery reserved mem's start address and size. Using DISCOVERY_TMR_OFFSET to init discovery_tmr_size instead.
