rcar-gen3: weston: Backport fix patch for Weston crashes issue
This backports the fix from [1]: Without universal plane, the weston crashes with null pointer access in set_gbm_format function because that function called before output enable function. By changing timing to set color format for primary plane in this case, this issue fixes.
