ARM: OMAP4470: Add voltage and dpll data
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 Signed-off-by: Taras Kondratiuk <taras@ti.com>
