powerpc: allow ioremap within reserved memory regions
Add a flag to let a platform ioremap memory regions marked as reserved. This flag will be used later by the Nintendo Wii support code to allow ioremapping the I/O region sitting between MEM1 and MEM2 and marked as reserved RAM in the patch "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.
