media: video: tegra: imx091: Fix pll_mult value

The pll_mult value for imx091 new mode [524x390]
is incorrectly set. Which is being used to derive
VtPixelClk and later this clock is used to calculate
coarse-time, frame-length and frame-rate, hence all
are being calculated to wrong values.
Slow-mo faces the incorrect fps issue when same mode
needs to be programmed with different fps.
