Disable ADPF CPU hints for SF unless active display is on

Currently AOD is bugged and does not always match refresh rate between
SF and HWC, which disrupts ADPF hint sessions in SF which are sensitive
to refresh rate (b/218066882). This patch disables ADPF CPU hints for
the AOD case until this issue is resolved.
