    feat: drm: split probe/attach lifecycle and fix radeon VBIOS ROM BAR
    
    Restructure i915/radeon/amdgpu to split PCI probe from drm_attach so
    the pdev lifecycle is valid for the entire driver lifetime.
    
    Add ROM BAR fallback in radeon_bios when vga_pci_alloc_resource fails,
    fixing VBIOS read on Apple EFI machines where the legacy ROM resource
    is not mapped.
