when there are some reasons which board failed to boot, eg rootfs crashes.
/init will fail to panic().
panic()
{
local console rest IFS
if command -v chvt >/dev/null 2>&1; then
chvt 1
fi
echo "$@"
# Disallow console access
if [ -n "${panic?}" ]; then
echo "Rebooting automatically due to panic= boot argument"
sleep "${panic}"
reboot
exit # in case reboot fails, force kernel panic
fi
...
}
when panic is set, there is no chance to fail into a shell, to debug what happens.
and device just keep reboot.
remove panic from bootargs to make it possible for users to find out why their boards fail to boot.

some armbian dts overlays currently do not work since pinctrl names have not been
adapted to renaming in 5.0 and 5.2.
this patch modifies the following overlays:
sun50i-h5: cir, spdif-out
sun8i-h3: cir, spdif-out
sun7i-a20: i2c1..4, mmc2, pwm, spdif-out, spi0..2, spi-add-cs1, uart4..7
