I'm not sure why you need this patch, I think we have a discuss
for the cpu operating point before.
In this case:
1. rk3288.dtsi is for all the rk3288 Soc based system, you may need
a separate opp table in rk3288-evb-rk808.dts;
2. 1.4V may beyond the supported voltage range too much,
and it's not a good idea to add it to rk3288.dtsi as a safe voltage.
3. Do you have a stress/heavy load test on evb with 1.4v at 1.8GHz?
