media: nxp: imx8-isi: Drop unneeded downscaling factor clamping
The total scaling factor including bi-linear downscaling and decimation
is clamped to 16. The bilinear factor calculation therefore produceds
values guaranteed not to exceed the maximum factor of 2.0. The clamping
is unneeded, drop it.
Note that the ISI_DOWNSCALE_THRESHOLD value of 0x4000 is incorrect, as
that would be a factor of 4.0. This was inconsequential given that the
computed factor never exceeded 0x2000.
