I see 3 steps:

1. In mir, expose API from graphics platform for powering on and off CRTCs. Expose to client API, i.e. mir_connection_request_display_power_mode (WIP :p). Likely this should be gated by a component:

msh::PowerManagementPolicy

Which receives messages like

bool session_is_allowed_to_turn_off_displays()

2. The system compositor gains a PowerManagementPolicy to allow XMir to turn off displays.

3. xmir gains a DPMS impl in terms of the new mir client API.
