zephyr: Add unused GPIOs implementation in shimmed gpio driver
This CL adds ununed GPIOs configuration support in shimmed gpio driver.
By adding IO phandles in 'unused-gpios' prop of board device-tree file,
the shimmed driver will configure them one by one (depends on board
circuit or io-pad design in chip) to prevent leakage current and get
better power consumption in the lowest power state.
