Hari Bathini 408cddd96e powerpc/fadump: Fix endianess issues in firmware assisted dump handling 
Firmware-assisted dump (fadump) kernel code is not endian safe. The
below patch fixes this issue. Tested this patch with upstream kernel.
Below output shows crash tool successfully opening LE fadump vmcore.
