powerpc: Change the default link address for pSeries zImage kernels
Currently we set the start of the .text section to be 4Mb for pSeries.
In situations where the zImage is > 8Mb we'll fail to boot (due to
overlapping with OF). Move .text in a zImage from 4MB to 64MB
(well past OF).
We still will not be able to load large zImage unless we also move OF,
to that end, add a note to the zImage ELF to move OF to 32Mb. If this
is the very first kernel booted then we'll need to move OF manually by
setting real-base.
