Tab5 audio, I2C improvements, UiDensity moved to lvgl-module and cleanup (#506)

- UiDensity moved to lvgl-module
- Deleted tt_hal and tt_hal_gpio (breaks apps, but will fix those right after merging)
- Added I2C 8 bit register operations
- Added device.properties to simulator
- Improved Tab5 hardware init, implement audio
- Add README.md to kernel
