[Intel-gfx] [PATCH v3 3/6] drm/i915: Add pipe_mode readout in verify_crtc_state

[Manasi Navare]

This adds new pipe_mode readout in verify_crtc_state()
Here it is just adjusted_mode without bigjoiner.
Bigjoiner pipe_mode readout will be added later.

While at it, create a separate intel_encoder_get_config()
function that calls encoder->get_config hook.
This is needed so that later we can add beigjoienr related
readout here.
