powerpc/64: flush_inval_dcache_range() becomes flush_dcache_range()
On most arches having function flush_dcache_range(), including PPC32,
this function does a writeback and invalidation of the cache bloc.
On PPC64, flush_dcache_range() only does a writeback while
flush_inval_dcache_range() does the invalidation in addition.
In addition it looks like within arch/powerpc/, there are no PPC64
platforms using flush_dcache_range()
This patch drops the existing 64 bits version of flush_dcache_range()
and renames flush_inval_dcache_range() into flush_dcache_range().
