Introduce scaler registers and bit fields needed to configure the scaling filter in prgrammed mode and configure scaling filter coefficients.
changes since v3: * None changes since v2: * Change macro names to CNL_* and use +(set)*8 instead of adding another trip through _PICK_EVEN (Ville). changes since v1: * None changes since RFC: * Parametrize scaler coeffient macros by 'set' (Ville)
