drm: mali-dp: add malidp_crtc_state struct
Add a custom CRTC state struct to enable storing driver's private state. This patch only adds the base drm_crtc_state struct and the atomic functions that handle it. Signed-off-by: Mihail Atanassov <mihail.atanassov@arm.com> Signed-off-by: Liviu Dudau <Liviu.Dudau@arm.com>
