[PATCH] hw/acpi: Set memory regions to native endian as a work around

[BALATON Zoltan <balaton@eik.bme.hu>]

When using ACPI on big endian machine (such as ppc/pegasos2 which has
a VT8231 south bridge with ACPI) writes to ACPI registers come out
byte swapped. This may be caused by a bug in memory subsystem but
until that is fixed setting the ACPI memory regions to native endian
makes it usable for big endian machines. This fixes ACPI shutdown with
pegasos2 when using the board firmware for now.
This could be reverted when the memory layer is fixed.
