The dtbdump.efi binary can already be used to dump the configuration table
with the device-tree to a file.
With this patch a device-tree file can be loaded. The EFI_DT_FIXUP_PROTOCOL
is called to
* apply U-Boot's fix-ups
* let U-Boot make memory reservations as required by the device-tree
* install the new device-tree as configuration table
In a next step this configuration table can be dumped.
A dtbdump.efi session would look like:
DTB Dump
========
=> load test.dtb
device-tree installed
=> save fixed-up.dtb
fixed-up.dtb written
=> exit

For validating the fixed up device tree we need a tool to need to save it
to a file.
dtbdump.efi copies the configuration table with the device tree to a file
on the same partition from which dtbdump.efi was invoked. The file name can
be entered on the console.
