Since, drm_crtc_vblank_on_config() was recently introduced, we want to apply laxer vblanking policies across the board, since: 1. It will allow us to shut down interrupts faster for better power savings. 2. As a payment towards tech debt, since drm_vblank_offdelay (which defaults to 5s) isn't necessary on AMD hardware. Also, patches 2-3 in this series provide even laxer policies and they are intentionally separated from patch #1. This way, if issues with them are encountered in the wild, it should be easy to bisect the issue to those patches.
