drm/i915: Clean up DP pipe select bits
Clean up the DP pipe select bits. To make the whole situation a bit
less ugly we'll start to share the same code between .get_hw_state(),
the port state asserts, and the VLV power sequencer code.
v2: Return PIPE_A for cpt/ppt when the port isn't selected by
any transcoder. Returning INVALID_PIPE explodes *somewhere*
on some machines (can't immediately see where though). This
now matches the old behaviour.
v3: Order the defines shift,mask,value (Jani)
