PMIC Auto-Probe via Base Class Interface

This example demonstrates automatic PMIC detection by probing multiple drivers on the I2C bus and accessing the detected device through the abstract PmicBase interface.

Architecture: PmicBase (abstract) ├── PmicSY6970 (Silergy, addr 0x6A) ├── PmicBQ25896 (TI, addr 0x6B) └── PmicAXP517 (X-Powers, addr 0x34)

Each driver's begin() validates the chip revision. The first successful probe selects the active PMIC. All subsequent access goes through the PmicBase pointer, demonstrating polymorphic PMIC control.
