The device should perform some startup self-tests on the I2C bus to verify everything is functioning nominally before starting the application.

Tests include:

Scanning all I2C mux channels and reading back the configured mux state
Read the EUI-48 identifier from EEPROM
Configure fans to 100% duty cycle, read back the RPMs and verify above known threshold. Repeat at 10% with different threshold
Configure DAC7571s on each channel to 3.2V bias voltage (disabled)
Configure ADS7924, set thresholds, verify no alarms are present.

Initial references to startup-procedures were discussed in #30
