Fix boot from NOR due to incorrect reset delay.

AT91 RSTC registers are battery-backuped, so their values
are not reset across power cycles. One of those registers,
the AT91_RSTC_MR register, is being modified by U-Boot, in
the ethernet initialisation routine, to generate a 500ms
user reset.

Unfortunately, this value is not being restored afterwards,
causing subsequent resets to also last for 500ms.

This long reset sequence causes problems (at least) in the
boot sequence from NOR: by the time the CPU tries to load
a program from the NOR flash, the latter is still in reset
and not yet available.

Additionaly, this patch fixes a bug in the original code which
caused the reset delay to last for 2s instead of 500ms.

Resize device tree to allow space for board changes and the chosen node

Current code requires that a compiled device tree have space added to the end to
leave room for extra nodes added by board code (and the chosen node).  This
requires that device tree creators anticipate how much space U-Boot will add to

tree when it needed more space, but this would require a systemic change to the
fdt code, which is non-trivial.  Instead, we resize the tree inside
boot_relocate_fdt, reserving either the remainder of the bootmap (in the case
