[PATCH V2 2/3] OMAP4: Update Voltage Rail Values for MPU/IVA

[Shweta Gulati]

Update MPU/IVA voltage Rail values obtained from
OMAP4430 Data Manual Operating Condition Addendum_v0.3.

Tested on OMAP4430 SDP Board.

Side note: unrelated to this patch: PMICs have discrete step sizes of 
10mV, 12.5, 25mV etc.. which makes something lik 1.118V probably not 
exactly possible on a PMIC with 25mV step. We need to next probably 
create a framework to round_up the voltages to the PMIC step size once 
the PMIC voltage layer changes are in.
