ARM: OMAP4470: Add voltage and dpll data

Browse Source 
OMAP4470 reference design uses TWL6032 PMIC
with a following connection scheme:
  VDD_CORE = TWL6032 SMPS2
  VDD_MPU  = TWL6032 SMPS1
  VDD_IVA  = TWL6032 SMPS5

Set voltage and frequency values according to
OMAP4470 Data Manual Operating Condition Addendum v0.7
