Currently all ODP_CACHE_LINE_SIZE macros for different architectures are
held in one header file, they should be moved to their own arch file.
This patch moves ODP_CACHE_LINE_SIZE for PowerPC.
The previous arch/powerpc/odp/cpu_arch.h was a symlink to the generic
arch/linux/odp/cpu_arch.h, but now this PowerPC header file has more
specific content than the generic one, so a real file is created and the
ODP_CACHE_LINE_SIZE is added to it.
