soc/intel/cmn/gfx: Fix GFX modeset issue with dual-display
This patch fixes the redundent GFX modeset issue when a dual display is attached (e.g. an eDP display and an HDMI display). The issue was caused by the MBUS joining logic not considering the display type. This patch introduces three types of display: internal, external, and dual-display. The MBUS joining logic is then updated to consider the display type and ensure that the correct pipes are joined to the MBUS: For internal-only displays, only PIPE-A is joined to the MBUS. For external displays, no pipes are joined to the MBUS. For dual-displays, all available pipes are joined to the MBUS. BUG=b:284799726 TEST=Able to fix the redundent modeset issue when eDP and HDMI attached to the google/rex.
