drm/amdgpu/discovery: reserve discovery data at the top of VRAM
IP Discovery data is TMR fenced by the latest PSP BL,
so we need to reserve this region.
Tested on navi10/12/14 with VBIOS integrated with latest PSP BL.
v2: use DISCOVERY_TMR_SIZE macro as bo size
use amdgpu_bo_create_kernel_at() to allocate bo
