vgsp: per-mdev emulated VRAM size (1.0 multiple mediate sizes)
- nv_vgpu_type_info/ioctl gain vram_mb; nv_vgpu_device gains fb_emul_size
bound from the mdev type at create (default 512 MiB).
- New nvidia-vgpu-turing-1g type (1024 MiB); turing max_instances 1 -> 2;
show_description reports the per-type framebuffer and max_instance.
- Thread fb_emul_size through GSCI fb_length/region/frtsOffset, WPR2,
NV_PFB_PRI_MMU_LOCAL_MEMORY_RANGE, the vidmem allocator bound and the BAR1
shadow; bar_info callback uses the per-device size.
- UNTESTED at commit time: builds clean; validation blocked by the Xid 140
incident (reboot pending). See Handoff-vGPU-IO.md ADDENDUM 48.
