RE: using nrf5340 and Zephyr OS , Is device binding and device tree the only way to use nrf5340's peripheral?

Yes, you can do this. Using lower layers may require more work, and you don't get all the advantages Zephyr comes with, but it is absolutely possible to use the functions in nrf_gpio.h and nrf_spim.h directly.

The nrfx layer is also an option (there is not an nrfx driver for GPIO, so you have to use nrf_gpio.h, like done here). You can take a look at the sample zephyr/samples/boards/nrf/nrfx to get an intuition on how to use the nrfx layer.

Best regards,
