Revert vc4/panel_cwu50 to boot.kernelModules (stage-2 loading)

Browse Source 
Loading via boot.kernelModules ensures they're loaded after
initrd, by which time RP1 PCIe southbridge is initialized (~12s).
This avoids the 'Cannot find any crtc' error from premature probe.

- boot.kernelModules: explicit vc4 + panel_cwu50 (stage-2)
- boot.initrd.kernelModules: only ocp8178_bl (backlight)
