drm/nouveau/kms/nv50: request vblank events for commits that send completion events
This somehow fixes an issue where sync-to-vblank longer works correctly after resume from suspend. From a HW perspective, we don't need the IRQs turned on to be able to detect flip completion, so it's assumed that this is required for the voodoo in the core DRM vblank core.

ed accesses, manipulating the FDT with the MMU off may result in alignment faults. So fix the situation by moving the update_fdt_memmap() call into the callback function invoked by efi_exit_boot_services() right before it calls the ExitBootServices() UEFI service (which is arguably a better place for it anyway) Note that disabling the MMU in ExitBootServices() is not compliant with the UEFI spec, and carries great risk due to the fact that switching from cached to uncached memory accesses halfway through compiler generated code (i.e., involving a stack) can never be done in a way that is architecturally safe.
