Fix reboot issue on ODROID-N2+ on Linux 5.10 (#1345)

In Linux 5.10.24 a regression has been introduced which broke reboot on
ODROID-N2(+). Interestingly the patch should improve reboot stability
for VIM3, which uses the same SoC. However, it seems that in the
ODROID-N2 case, this causes more problems then it fixes. Revert the
offending patch.
