Core2 M5Unified independence + general fixes (#142)
- Change init sequence: I2C is now initialized before "power" init phase, to allow for I2C power control
- I2c HAL: Added read/write support for registers
- Added axp192 code from https://github.com/tuupola/axp192 to Core2 implementation
- Fixes for Core2Power
- Fix for root project CMakeLists.txt
