pinctrl: qcom: spmi-gpio: add support for LV_VIN2 and MV_VIN3 subtypes
Add support for SPMI PMIC GPIO subtypes GPIO_LV_VIN2 and GPIO_MV_VIN3. GPIO_LV_VIN2 GPIOs support two input reference voltages: VIN0 and VIN1. These are typically connected to 1.8 V and 1.2 V supplies respectively. GPIO_MV_VIN3 GPIOs support three input reference voltages: VIN0, VIN1, and VIN2. These are typically connected to Vph, 1.8 V, and 1.2 V supplies respectively.
