[Intel-gfx] [PATCH v2 3/5] drm/i915: Introduce scaling filter related registers and bit fields.

[Pankaj Bharadiya]

Introduce scaler registers and bit fields needed to configure the
scaling filter in prgrammed mode and configure scaling filter
coefficients.

changes since v1:
* None
changes since RFC:
* Parametrize scaler coeffient macros by 'set' (Ville)
