ARM: dts: exynos: Adjust buck[78] regulators to supported values on Odroid XU3 family
The datasheet of S2MPS11 PMIC is slightly non-consistent in buck[78]
voltage regulators values.
1. The voltage tables for configuring their registers mention range of
voltages: 0.750 V to 3.55 V,
2. The constrains in electrical specifications say output voltage range
to be different (buck7: 1.2 V to 1.5 V, buck8: 1.8 V to 2.1 V).
Adjust the ranges to match the electrical specifications to stay on the
safe side. Also change the name of regulators to match reality. Anyway
these regulators stay at default value so this should not have effect.
