[ Upstream commit 0ee9f600e69d901d31469359287b90bbe8e54553 ]

Function sun8i_vi_layer_get_csc_mode() is supposed to return CSC mode
but due to inproper return type (bool instead of u32) it returns just 0
or 1. Colors are wrong for YVU formats because of that.

Fixes: daab3d0e8e2b ("drm/sun4i: de2: csc_mode in de2 format struct is mostly redundant")
