[U-Boot] CFG_64BIT_xxx and friends

[Matthias Fuchs <matthias.fuchs@esd-electronics.com>]

Here is the U-Boot size for the PLU405 board (405EP-based) with
and without

#define CFG_64BIT_VSPRINTF
#define CFG_64BIT_STRTOUL
.

without:
# ppc_4xx-size u-boot
   text    data     bss     dec     hex filename
 289568   17532  301312  608412   9489c u-boot

with 64bit format handling:
# ppc_4xx-size u-boot
   text    data     bss     dec     hex filename
 291368   17532  301312  610212   94fa4 u-boot

So the difference is 1800 bytes on this architecture.
