Empty initrd for display, add rp1_dsi module

Browse Source 
ALL RP1 hardware (gpio, clocks, dsi) sits behind the RP1 PCIe
southbridge, which isn't ready until ~12s. Loading any display
module in initrd (~3s) crashes the system. Nothing in initrd now:
- boot.initrd.kernelModules: empty (nothing touches RP1 early)
- boot.kernelModules: vc4, panel_cwu50, rp1_dsi (stage-2)
