clocksource/drivers/dw_apb_timer: Inline apbt_readl and apbt_writel
It seems gcc can automatically inline apbt_writel() for us, but apbt_real isn't inlined. This patch makes them inline to get a trivial performance improvement: 4096 rounds of __apbt_read_clocksource() call spend time on Marvell BG4CT platform: before the patch 1275240ns on average after the patch 1263240ns on average so we get 1% performance improvement.
