kms/update: Make power saving an update wide change

Browse Source 
This makes "power save" (i.e. when you make a monitor go into power save
mode, or make it come out of power save mode), a per device action when
turning on power saving (power save being set to 'off'), and implicitly
handled when turning off power saving (power save being set to 'on')
when doing a mode set.

This is needed as with atomic mode setting, the configuration of DPMS
(Display Power Management Signaling), is replaced by directly turning on
or off CRTCs, and via the CRTC drm properties. Thus in order to handle
both with a common API, make that API high level enough for both cases
being covered.
