These two patches try to improve the dw_apb_timer clocksource/clockevent
performance.
since v2:
- only use relaxed version in critical path
- inline apbt_readl/apbt_writel
- add some performance numbers
since v1:
- correct the wrong sentence in commit msg about writel performance on
CA9 with outer L2 cache. Thank Arnd for pointing out this in another
thread.
