drm/i915/display: convert params to struct intel_display

Going forward, struct intel_display shall replace struct
drm_i915_private as the main display device data pointer type. Convert
intel_display_params.[ch] and intel_display_debugfs_params.[ch] to
struct intel_display.

Some stragglers are left behind where needed.
