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 Signed-off-by: Xiaojie Yuan <xiaojie.yuan@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
