Arduino Compat starts before dependencies are initialized

[gsc-dev]

I am specially impacted by the mgos spi lib as the arduino code in setup() sends comms before mgos_spi_create is fired.

Work-around that worked for me:

enum mgos_app_init_result mgos_app_init(void) {
  do_setup();
  return MGOS_APP_INIT_SUCCESS;
}
