Make the autoboot work :
- if no USB cuable is plugged, continue directly to
autoboot
- if an USB cable is plugged, wait for 3 seconds for
any input on the USB serial gadget, and if none
happens, continue to autoboot linux kernel
- else interrupt autoboot and interact on barebox
console

In order for barebox to be functional, the docg3 DPS1 has to
protect barebox from writes, and have its embedded IPL coded
to load barebox (as barebox is the SPL).
Add a raw DPS1, which :
- protects the area from block 6 to block 123
This is DPS1 + barebox + barebox-logo
- encodes the 2048 bytes IPL

To speed-up linux kernel loading, switch the PXA cpu to the
maximum allowed frequency (520 MHz). This improves the load
time from several seconds to less than a second from the
MTD.

Add a check to verify if /barebox.BIP0 exists, and if so,
unlock the protection area, flash barebox, and reprotect the
area.
