drivers: flash: replace DT_FLASH_DEV_NAME with DT macro

Browse source 
Replace DT_FLASH_DEV_NAME with DT_CHOSEN_ZEPHYR_FLASH_CONTROLLER_LABEL.
We now set zephyr,flash-controller in the chosen node of the device
tree to the flash controller device.

NOTE: For a SoCs with on die flash, this points to the controller and
      not the 'soc-nv-flash' node.  Typically the controller is the
      parent of the 'soc-nv-flash' node).
