`adxl.cfg` needs to be modified for Klipper to work

[Galloant]

In the original adxl.cfg, the adxl is configured as an MCU, which brakes the printer down on restart. Needs to be modified to the following for it to work:

[adxl345]
cs_pin:mcu1:gpio13
spi_software_sclk_pin:mcu1:gpio14
spi_software_mosi_pin:mcu1:gpio15
spi_software_miso_pin:mcu1:gpio12

[resonance_tester]
accel_chip: adxl345
min_freq: 5
max_freq: 90
accel_per_hz: 150
hz_per_sec: 2
probe_points:
probe_points:
    400, 400, 50

When changing the adxl.cfg, the passage in printer.cfg which defines the adxl can be removed.
