Summary

Add a Raspberry Pi 4B usage tutorial to the Radxa Display 8 HD usage page (zh + en), resolving the missing Raspberry Pi documentation reported in #519.

The new tab documents, based on the official radxa-displays-on-raspberry-pi repository:

  • FPC wiring from the display's 7-pin holder to the Raspberry Pi 4B 40-pin GPIO (VCC-5V / GND / BL-PWM / TP-RST / TP-INT / LCD-RESET)
  • DKMS kernel driver install (panel-radxa-dsi-dkms)
  • config.txt overlay configuration (vc4-kms-dsi-radxa-panel) and reboot steps

Why

Users asked how to use Radxa Display 8 HD on Raspberry Pi; the official driver repo already documents this, but the docs page only covered Radxa SBCs (4C+/5A/5B, 3A/3C/4SE). This change closes the gap with a link to the canonical upstream guide.

Fixes #519

Add a Raspberry Pi 4B tab to the Radxa Display 8 HD usage page (zh/en),
based on the official radxa-displays-on-raspberry-pi repository guide:
FPC wiring to the 40-pin GPIO, DKMS driver install and config.txt overlay.

Fixes radxa-docs#519
