Investigatory stand/powerpc/ofw/ofwfdt.c and sys/contrib/libfdt/fdt_rw.c
patches

stand/powerpc/ofw/ofwfdt.c is updated because:

A) ofwfdt_fixups had the odd mix for context handling:

G3's/G4's (4,1 and 3,6 PowerMac examples) eliminated /memory at 0/available
but. . .
G5's (7,2 and 11,2 examples) did not eliminate /memory0,0/available

Now it does both.

B) fdt_platform_load_dtb did no checking of return status values
or reporting of its own of such failures.


Note: sys/contrib/libfdt/fdt_rw.c is unchanged.
