[U-Boot] add usb_system_autoupdate command.

[Matteo Facchinetti <matteo.facchinetti@sirius-es.it>]

Hi Marco,

I looked updater.c and and I take that code as example.

Well,
I removed all function as same as do_... (do_fat_fsload, do_protect, 
do_flerase, do_mem_cp).
In this way, I could remove also strcpy() and sprintf() needed to made 
their parameters and the result is that I cleaned and emproved all code.

Now all works correctly.
I think that the rewrite of the code, indirectly solve some bugs of 
memory corruption.

In attach, the code...
and if anyone try it, I'm interesting to feedback or opinions.

Thanks at all.
Matteo.
