This commit adds support for the AXP2101 Power Management IC (PMIC). Features: - Hub component for I2C communication with AXP2101 - Sensor support for monitoring: - Battery voltage, level (percentage) - VBUS voltage - VSYS voltage - Die temperature - Switch support for enabling/disabling power rails: - 5 DCDC regulators (DCDC1-5) - 11 LDO regulators (ALDO1-4, BLDO1-2, CPUSLDO, DLDO1-2) - Number support for voltage control of all power rails - Each rail supports its specific voltage range and step size - Comprehensive test configurations for ESP32, ESP8266, and RP2040 The component follows ESPHome patterns with a hub-based architecture allowing sensors, switches, and numbers to reference the main component.
