media: rockchip: rkisp1: reduce number of histogram grid elements in uapi

Browse source 
The uapi right now specifies an array size of 28 but the actual number
of elements is only 25 with the last 3 being unused.

Reduce the array size to the correct number of elements and change
the params code to iterate the array 25 times.
