cmd: fdt: Print error message when fdt application fails

There are lots of reason why a FDT application might fail, the
error code might give an indication. Let the error code translate
in a error string so users can try to understand what went wrong.

cmd/fdt: fix uncallable systemsetup command

The function that is processing the 'fdt' parameters is one big
if-else if. In order to be able to type command faster only the first
few letter are checked to know which block of code to execute. For
systemsetup, the block of code that was executed was always the wrong
one and ended up in a failure.

} else if (argv[1][0] == 's') {
process "fdt set" command
} else if (strncmp(argv[1], "sys", 3) == 0) {
process "fdt systemsetup" command.
}

When typing "fdt systemsetup", the code that was executed was the code
for "fdt set".

This commit fix this issue by moving the "else if" for systemsetup
before the else if for "fdt set". This allow us to keep compatibility
with any script that make use of "fdt s" to set node values.

cmd/fdt: add possibilty to have 'extrasize' on fdt resize

Sometimes devicetree nodes and or properties are added out of the u-boot
console, maybe through some script or manual interaction.

The devicetree as loaded or embedded is quite small, so the devicetree
has to be resized to take up those new nodes/properties.

In original the devicetree was only extended by effective
4 * add_mem_rsv.

With this commit we can add an argument to the "fdt resize" command,
which takes the extrasize to be added.

cmd: fdt: add fdt overlay application subcommand

The device tree overlays are a good way to deal with user-modifyable
boards or boards with some kind of an expansion mechanism where we can
easily plug new board in (like the BBB or the raspberry pi).

However, so far, the usual mechanism to deal with it was to have in Linux
some driver detecting the expansion boards plugged in and then request
these overlays using the firmware interface.

That works in most cases, but in some cases, you might want to have the
overlays applied before the userspace comes in. Either because the new
board requires some kind of an early initialization, or because your root
filesystem is accessed through that expansion board.

The easiest solution in such a case is to simply have the component before
Linux applying that overlay, removing all these drawbacks.
