On Exynos5422/5800 the regulator supply for the A15 cores ("vdd_arm") is
coupled with the regulator supply for the SoC internal circuits
("vdd_int"), thus all operating points that modify one of those supplies
have to specify a triplet of the min/target/max values to properly work
with regulator coupling.
