arch/arm: Fix error in cache ops

[zyfeier]

Summary

1. Cache function should depends on CONFIG_ARCH_XCACHE;
2. Add invalidate icache function for armv7ar;
3. Add cp15_invalidate_icache for invalidate the instruction cache within the specified region;
4. Fix typo error in cp15_cacheops.h;
5. Add barrier instruction for cache ops;
6. Flush dcache when addr is not aligned with cache line;

Impact

cache ops
