That's wrong for two reasons: 1. Two different devices cannot have the same iostart in devicetree, as those would technically be the same device otherwise; and 2. SVS and Thermal Sensor (be it LVTS or AUXADC thermal) are not the same IP, and those two do obviously have a different iospace. Even though there already are users of this register array, the only one that declares a devicetree node for SVS is MT8183 - but it never actually worked because the "tzts1" thermal zone missed thermal trips, hence this driver's probe always failed on that SoC. Knowing this - it is safe to say that keeping compatibility with older device trees is pointless, hence simply subtract the 0xc00 offset from the register offset array.
