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

Browse Source 
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.

All ODROID-N2 boards come with a NXP PCF8563TS RTC connected to I2C bus
3. This is the RTC which is connected to the on-board RTC backup battery.
