But rebuilding scaler state from hw requires,
- reading all planes and find its corresponding index

During readout_hw_state, whole pipe_config is built reading hw.
But rebuilding scaler state from hw requires,
- reading all planes and find its corresponding index in order to set
its bits in scaler_users
- reading cdclk and adjusted mode crtc clk in order to regenerate
min scaling ratios.
