drm/rockchip: vop: Fix reset of state in duplicate state crtc funcs

Browse Source 
struct rockchip_crtc_state members such as output_type, output_bpc and
enable_afbc is always reset to zero in the atomic_duplicate_state crtc
funcs.

Fix this by using kmemdup on the subclass rockchip_crtc_state struct.
