uboot-mediatek: fix factory/reset button

U-Boot commit ea6fdc13595 ("dm: button: add support for linux_code in
button-gpio.c driver") makes it mandatory to specify linux,code for all
buttons. As that broke handling of the reset button in U-Boot with the
update to U-Boot 2023.04, add linux,code for all butons.

Reported-by: @DragonBluep
Fixes: 50f7c5af4a ("uboot-mediatek: update to v2023.04")
