[Pixman] [PATCH] ARM: NEON: use prefetch in bilinear scaled 'src_8888_8888'

From: Siarhei Siamashka Software prefetch significantly improves bilinear scaling performance and pushes it up to memory bandwidth limit. Benchmark on ARM Cortex-A8: Microbenchmark (scaling 2000x2000 image with scale factor close to 1x): before: op=1, src=2002, dst=2002, speed=44.27 M
