powerpc: wii: allow ioremap within the memory hole
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.
