Fix: Configure ADXL345 as separate device (not in cartographer section)

The 'accel_chip' option is not valid in [cartographer] section.
ADXL345 must be configured as a separate [adxl345] device that
communicates via the Cartographer MCU.

Correct configuration:
- [adxl345] with cs_pin: cartographer:PA3 and spi_bus: spi1
- [resonance_tester] with accel_chip: adxl345
- [cartographer] does NOT include accel_chip

This fixes: 'Option accel_chip is not valid in section cartographer'
