[PATCH] drm/meson: fix max mode_config height/width

The mode_config max_width/max_height determines the maximum framebuffer
size the pixel reader can handle. But the values were set thinking they
were determining the maximum screen dimensions.

This patch changes the values to the maximum height/width the CANVAS block
can handle rounded to some coherent values.
