drm/i915: Do the DRIVER_ATOMIC feature disable later
Currently we do the DRIVER_ATOMIC disable as almost the
first thing during pci probe. That involves the use of
DISPLAY_VER() which is perhaps a bit sketchy now that we
may need to read that out from the hardware itself.
Looks like we do populate a default value for it anyway
so the current does at least still work.
But let's make this safer anyway and move the code
into intel_device_info_runtime_init() where we also
handle the same thing for the !HAS_DISPLAY case.
