video: dw_mipi_dsi: Fix hsync/vsync settings
These must be read from timings->flags, like other DSI HOST drivers do.
And they must not be inverted either. Low means low.
Without this fix, panel drivers that set *SYNC_LOW produce corrupted
output on screen (shifted horizontally and vertically by back porch
distance).
