drm/arcpgu: replace struct drm_simple_display_pipe with regular atomic helpers

Browse source

Instantiate the primary plane, CRTC and encoder directly and wire them up
with standard atomic helpers.

Move the simple-pipe callbacks into explicit plane and CRTC helper
callbacks. Use commit-local CRTC and plane state in the CRTC enable path
for mode and pixel-format programming.

Handle missing remote encoder nodes explicitly and take the CRTC modeset
lock while reading CRTC state from debugfs.
