drm/amdgpu: keep vga memory on MacBooks with switchable graphics
On Intel MacBookPros with switchable graphics, when the iGPU
is enabled, the address of VRAM gets put at 0 in the dGPU's
virtual address space. This is non-standard and seems to cause
issues with the cursor if it ends up at 0. We have the framework
to reserve memory at 0 in the address space, so enable it here if
the vram start address is 0.
