video: mxsfb: fix pixel clock polarity
DISPLAY_FLAGS_PIXDATA_NEGEDGE means the controller drives the data on
pixel clocks falling edge. That is DOTCLK_POL=0 (default) not 1.
The mxsfb-drm driver in the Linux kernel has made the same change and it
remains to this day:

I found this was required on an IMX8X SoM.
Without the patch a splash screen displays with aliasing-like jagged edges.
