As discussed in the long thread about vblank related timeouts, it turns out
GM45 has different frame count registers than previous chips. This patch
adds support for them, which prevents us from waiting on really stale
sequence values in drm_wait_vblank (which rather than returning immediately
ends up timing out or getting interrupted).
