drm/sysfb: vesadrm: Support power management

Browse source

Set PM ops for the vesadrm driver. Suspend and resume the DRM state
on systems that support it.

Many systems lose the hardware's framebuffer settings on suspend,
hence resuming doesn't work there. Yet some systems, most notably
emulators, keep the hardware state across suspend/resume cycles.
There, DRM's suspend and resume helpers bring back the display on
resume.
