Reserved VRAM is used to avoid overriding pre OS FB.
Once our display stack takes over we don't need the reserved
VRAM anymore.
v2:
Remove comment, we know actually why we need to reserve the stolen VRAM.
Fix return type for amdgpu_ttm_late_init.
v3:
Return 0 in amdgpu_bo_late_init, rebase on changes to previous patch
v4: rebase
v5:
For GMC9 reserve always just 9M and keep the stolem memory around
until GART table curruption on S3 resume is resolved.

Steal 9 MB for vga emulation and fb if vga is enabled, otherwise,
steal enough to cover the current display size as set by the vbios.
If no memory is used (e.g., secondary or headless card), skip
stolen memory reserve.
v2: skip reservation if vram is limited, address Christian's comments
v3: squash in fix from Harry

it provides a write and wait in a single packet which avoids a missed
ack if a world switch happens between the request and waiting for the
ack.

back another register and waits for a value in a single

that don't support this opertion.
