powerpc: Only use initrd_end as the limit for alloc_bottom if it's inside the RMO.

Browse source

As the kernels and initrd's get bigger boot-loaders and possibly
kexec-tools will need to place the initrd outside the RMO.  When this
happens we end up with no lowmem and the boot doesn't get very far.

Only use initrd_end as the limit for alloc_bottom if it's inside the
RMO.
