drm/i915: Enable scaling filter for plane and CRTC
GEN >= 10 hardware supports the programmable scaler filter.
Attach scaling filter property for CRTC and plane for GEN >= 10
hardwares and program scaler filter based on the selected filter
type.
changes since v3:
* None
changes since v2:
* Use updated functions
* Add ps_ctrl var to contain the full PS_CTRL register value (Ville)
* Duplicate the scaling filter in crtc and plane hw state (Ville)
changes since v1:
* None
Changes since RFC:
* Enable properties for GEN >= 10 platforms (Ville)
* Do not round off the crtc co-ordinate (Danial Stone, Ville)
* Add new functions to handle scaling filter setup (Ville)
* Remove coefficient set 0 hardcoding.
