Hi,

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.

If we are removing gen check, then IMHO we should initialize "scaler_id
= -1" even before !crtc->num_scalers check in intel_crtc_init_scalers
function, just to make sure scaler state doesn't have wrong value in
platforms where we don't have any scalers.
