disp: msm: Pass the full state to crtc plane and connector atomic functions

Pass full state to crtc, plane, and connector atomic functions and retrieve
drm_crtc/plane/connector_state within the atomic function. Additionally,
the plane atomic update function is used as an upstream hook as well as
locally called in the plane restore path. To ensure both paths are functional,
introduce a plane atomic update version which takes in drm_plane_state
keeping with the previous parameter expectations.
