drm/amdgpu: reduce early full GPU access during SR-IOV init

Allow early FB reads to fall back to BAR0 when the VRAM aperture is not ready.
This lets SR-IOV VFs consume host-provided init data before requesting full GPU access.

For ASICs that support request_init_data,
defer full GPU access until after non-GPU early init to shorten the full-access window.

Legacy ASICs(before NV12) do not send request_init_data;
the host dumps init data only during full GPU access,
so keep the original early full-access request path for them.
