Guoniu Zhou 5eb54da3f8 media: nxp: imx8-isi: Fix scale factor calculation for hardware rounding 
The ISI hardware rounds the actual output size up to an integer, as
described in i.MX93 Reference Manual section 57.7.8 (Channel 0 Scale
Factor). The scale factor must be calculated to ensure the theoretical
output value rounds up to exactly the desired size.
