video: tegra: imx091: lower max VI clock to 204MHz
Lower the max VI clock for imx091 from 250MHz
to 204MHz. This is to match what is currently
specified in the sensor mode table. This is done
by lowering the clock multiplier from 10.41667
to 8.5(24MHz * 8.5 = 204MHz).
On some older T114 platforms, we are not able to
set VI clock to 250MHz due to the slower memory
clock. This will end up slowing our VI_SENSOR
clock and make frame rate lower.
