[PATCH] drm/arcpgu: use .mode_fixup instead of .atomic_check

Since we cannot always generate exactly requested pixel clock there's not much sense in checking requested_clock == clk_round_rate(). In that case for quite some modes we'll be getting -EINVAL and no video output at all. But given there's some tolerance to real pixel clock in TVs/monitors we may s
