[PATCH 08/10] drm/nouveau: Implement vga_switcheroo_client_ops.post_switch

An output's attached display might have changed while a DRM client's
device did not have the output switched to it.

The nouveau_switcheroo_reprobe() callback sends a hotplug notice to
DRM's internal clients, wo that they can reconfigure their display
output if necessary.

As post_switch callback replaces reprobe in vga_switcheroo, update
nouveau accordingly. No functional changes.
