drm/amd/display: fix S/G display enablement

An assignment statement was reversed during a refactor which effectively
disabled S/G display outright. Since, we use
adev->mode_info.gpu_vm_support to indicate to the rest of the driver
that S/G display should be enabled and currently it is always set to
false. So, to fix this set adev->mode_info.gpu_vm_support's value to
that of init_data.flags.gpu_vm_support (and not vice versa).
