[PATCH 3/4] arm: layerscape: ppa: reserve SDRAM region for PPA

[Sascha Hauer]

The region the PPA is stored may not be speculated into by the CPU.
We have reserve_sdram_region() for this purpose. With this the region
is mapped uncached with excute never bit set. Use this rather than
request_sdram_region().
