[PATCH] powerpc: Fix zImage decompress location

[Benjamin Herrenschmidt]

The zImage wrapper has a "hack" that force the decompression to happen
above 20Mb for 64 bits kernels, to work around issues with some
firmwares on the field. However, the new wrapper has a bug which makes
that hack not work properly. This fixes it.
