[media] omap3isp: resizer: Use 4-tap mode equations when the ratio is <= 512

As the number of phases/taps, used to select the correct equations to
compute the ratio, depends on the ratio, start with the 7-tap mode
equations to compute an approximation of the ratio, and switch to the
4-tap mode equations if the approximation is lower than or equal to 512.
