Add support for Toradex Verdin AM62P computer on module which can be used on different carrier boards and for the Toradex Verdin Development Board carrier board. The module consists of an TI AM62P family SoC, a TPS65219 PMIC, a Gigabit Ethernet PHY, up to 8GB of LPDDR4 RAM, an eMMC, a TLA2024 ADC, an I2C EEPROM, an RX8130 RTC, plus an optional Bluetooth/Wi-Fi module. Anything that is not self-contained on the module is disabled by default.
