drm/i915: Move encoder suspend/shutdown helpers to intel_encoder.c

Move the encoder suspend/shutdown helpers to intel_encoder.c, this being
the logical place for encoder functions.

This also allows sharing the above helpers with the xe driver, done in a
follow-up patch.

While at it rename the functions using the usual intel_encoder prefix
and in the functions rename the dev_priv parameter to i915.

v2: Remove extra w/s in the include section. (Jani)
