[PATCH] powerpc/pasemi/nemo: Fix low memory values for boot.

[Darren Stevens]

Commit 5c0484e25ec0 ('powerpc: Endian safe trampoline') added a
macro 'FIXUP_ENDIAN' to head_64.S. The CFE on Nemo has a bug 
that shows up when this is included, the system hangs right after
printing the initial memory map, before the CPU's are started.

Clearing the long long at addr 8 has been shown to fix this, so
add an initalisation to head_64.S so the system will boot.
