ARM: 5635/1: Use DIV_ROUND_CLOSEST

Browse source 
The kernel.h macro DIV_ROUND_CLOSEST performs the computation
(x + d/2)/d but is perhaps more readable.

The semantic patch that makes this change is as follows:

expression x,__divisor;

- (((x) + ((__divisor) / 2)) / (__divisor))
+ DIV_ROUND_CLOSEST(x,__divisor)
// </smpl>
