Martin Bauer 6b9b50ef2e Get sound, the screen and emoji working on musicdolphin's Pi 5 ...

- HiFiBerry: the plain hifiberry-dacplus overlay makes the Pi the I2S clock consumer,
  which the Pi 5's controller refuses (snd_soc_dai_set_fmt -22). The card never probed,
  so every softvol_* device was dead: squeezelite crash-looped and the backend and
  shairport played into nothing. hifiberry-dacplus-std has the Pi drive the clocks.
  pi_hifiberry_amp now matches any dtoverlay=hifiberry-* line, so changing the overlay
  replaces the old one instead of adding a second.
- X: with two DRM devices (v3d, vc4) Xorg gave up with "Cannot run in framebuffer
  mode", and the kiosk looped on a blank screen. 99-vc4.conf points it at vc4, the
  display controller; rendering still goes to V3D (glxinfo: V3D 7.1, accelerated).
- The front-end's icons are emoji in the markup. The Lite image has no emoji font, so
  they rendered as empty boxes: install fonts-noto-color-emoji.
