Subject: [PATCH] drm/i915: Simplify scaler init during CRTC HW readout
Git-commit: e79dfb512110ce6759f139a286f0e1d6bc5e4c58
Patch-mainline: v4.14-rc1
References: FATE#322643 bsc#1055900

The crtc state starts out being bzero'd, so no need to clear
scaler_users. Also intel_crtc_init_scalers() knows already which
platforms have scalers, so no need for the platform check here.
Similarly intel_crtc_init_scalers() will init scaler_id as required,
so no need to do it here separately.
