ARM: dts: msm: Adjust the NOM corner CPR configuration for 8939 



Add changes to
- Move 1.036 GHz and 1.113 GHz into NOM corner
- Selectively adjust CPR quotient offset in NOM corner
- Selectively adjust the floor-voltage in NOM corner

This change is to improve the performance by including higher
frequencies into the NOM corner. It also reduces the power
impact by allowing these frequencies to run at lower voltages.
