powerpc: wii: allow ioremap within the memory hole

Browse Source 
Enable the flag that allows a platform to ioremap memory marked
as reserved.

This is currently needed on the Nintendo Wii video game console
due to the workaround introduced in "wii: use both mem1 and mem2 as ram".

This will no longer be needed when proper discontig memory support
for 32-bit PowerPC is added to the kernel.
