This patch updates the voltage levels for VDD1 OPP1/2 and
VDD2 OPP1/2 according to the latest operating condition
addendum for 3430.

The new voltage levels at various OPP's for VDD1/2 are as below

VDD1 OPP1 0.975v
VDD1 OPP2 1.050v
VDD1 OPP3 1.200v
VDD1 OPP4 1.270v
VDD1 OPP5 1.350v

VDD2 OPP1 0.975v
VDD2 OPP2 1.050v
VDD2 OPP3 1.150v

The patch applies on the latest pm head and is validated on 3430SDP.

I have tested Bridge DVFS and OFF mode with this patch, This works fine and it resolved the issues I was seeing with OPP1. 

Thanks

This didn't apply to latest PM branch due to changes in the regbits
header.  I manually fixed this up and applied to PM branch.

Thanks,
