clocksource: Fix type confusion for clocksource_mmio_readX_Y
The types' definations are: o cycle_t -> u64 o readl_relaxed -> u32 o readw_relaxed -> u16 So let clocksource_mmio_readX_Ys return a cast to cycle_t, though this maybe look reduntant sometimes, it make sense and they will be more readable and less confusion... This patch clarifies the functions type and fix it.
