I'd say we've simply lucked out thus far. E.g. on vlv the
init_clock_gating flushes the primary plane and so casues a flip done
interrupt. But right now we call that clock gating stuff after crtc
init so we're good. So my concern isn't that this can't be done but
that it's fragile. And right now we don't have any infrastructure to
help with the driver boostrapping at all, but we've had tons of cases
where things blew up in funny way. So good ideas welcome.
