MLK-18000: drm: imx: dcss: compute filter coeff based on scaling ratios

Currently, scaler filter coefficients are hardcoded. However, they need
to be re-computed, based on input/output resolution as well.

Also, in order to use the scaler 7-tap filter, DPR RTRAM rows need to be
changed accordingly.
