Rex timing: remove vc4/panel_cwu50 from boot.kernelModules too

Let udev auto-load display modules when RP1 PCIe southbridge
appears on the bus (~12s). This is exactly how Rex's Debian
image works — no forced loading in initrd or stage-2.

- boot.initrd.kernelModules: only ocp8178_bl (backlight only)
- boot.kernelModules: no display modules (udev handles it)
- SDDM disabled (Hyprland kept for manual start)
