Add scaling factors to scaler_state for a perticular scaler user,
use it later to compute scaler prefill latency. Also to extend this
when either pipe or plane scaler is in use.

Add enum to track scaler user, this differenciates between
the current user of scaler, either plane scaler/pipe scaler or
in case no scaler is used.

Parse crtc_state to intel_atomic_setup_scaler, this will help to
check if pch_pfit enabled or not and also will be useful to parse
scaler_state with the same.

Probably should fill these in skl_scaler_get_config() and add in
intel_pipe_config_compare() to compare.

This is not required, we can use the flag 'scaler_users'.
Also as I see, this is not used in the series.

typo: pipe scaling.
There is a #FIXME to check scalar factors for pfit, so with this we can
remove that.
There are some considerations for joiner, there are patches for that in
review. [1]

This will not work. We need to take proper precision into account to do
this calculation.
currently hscale,vscale are left shifted by 16.

As mentioned in previous patch, hscale and vscale are left shifted
values, need to compute this precisely.
Also as per spec for pipe scaler is used for 444 to 420 conversion.
Chroma subsampling is a 2x downscale. So need to account for it.

Thanks for the review Ankit,
It seems, we do readout only for pipe during skl_scaler_get_config, where as we are computing hscale and vscale for plane as well. While readout it may create mismatch.
Wanted to bring for more discussion, I have addressed comments on rest other patches.
Again Thanks.
