timeval: Reorder elements in clock structure.

By reordering the elements in clock structure, pad bytes can be reduced and also a cache line is saved. Before: structure size:136, holes:3, sum padbytes:18, cachelines:3 After: structure size:120, holes:1, sum padbytes:2, cachelines:2 Signed-off-by: Bhanuprakash Bodireddy <[email protected]> Co-authored-by: Antonio Fischetti <[email protected]> Signed-off-by: Antonio Fischetti <[email protected]> Acked-by: Jarno Rajahalme <[email protected]> Acked-by: Daniele Di Proietto <[email protected]>
