drm: exynos: dsi: Add input_bus_flags

Browse source

LCDIF-DSIM glue logic inverts the HS/VS/DE signals and expecting
the i.MX8M Mini/Nano DSI host to add additional Data Enable signal
active low (DE_LOW). This makes the valid data transfer on each
horizontal line.

So, add additional bus flags DE_LOW setting via input_bus_flags
for i.MX8M Mini/Nano platforms.
