Move the logic for converting a node to text from

Provide a wrapper function convert_device_node_to_text_ext.

As we use only shallow device paths so we can call
directly call efi_device_node_to_text from efi_device_path_to_text.

Add output for MAC addresses.

Add output for not yet supported types/subtypes.

The efi_loader currently stops iterating over the available
block devices stopping at the first device that fails.
This may imply that no block device is found.

With the patch efi_loader only iterates over valid devices.

It is based on patch
06d592bf52f6 (dm: core: Add uclass_first/next_device_check())
which is currently in u-boot-dm.git.

For testing I used an odroid-c2 with a dts including
&sd_emmc_a {
status = "okay";
};
This device does not exist on the board and cannot be initialized.

Without the patch:
