Connect i2c display to DIY pikvm

The main problem is that i2c doesn’t come enabled by default.

Steps

• su (default password is root)
• rw to be able to edit files
• Add dtparam=i2c_arm=on to /boot/config.txt
• Create a file /etc/modules-load.d/i2c-dev.conf with the content i2c-dev
• systemctl enable kvmd-oled kvmd-oled-reboot kvmd-oled-shutdown
• ro
• reboot
