Add the required SC register configurations which lets us perform linear scaling for the supported range of horizontal and vertical scaling ratios. The horizontal scaler performs polyphase scaling using it's 8 tap 32 phase filter, decimation is performed when downscaling passes beyond 2x or 4x. The vertical scaler performs polyphase scaling using it's 5 tap 32 phase filter, it switches to a simpler form of scaling using the running average filter when the downscale ratio is more than 4x. Many of the SC features like peaking, trimming and non-linear scaling aren't implemented for now. Only the minimal register fields required for basic scaling operation are configured. The function to configure SC registers takes the sc_data handle, the source and destination widths and heights, and the scaler address data block offsets for the current context so that they can be configured.
