disp: msm: adapt crtc plane and connector atomic functions for multiple SIs

Commit ddac29b ("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.
This change puts macros in the callers of atomic functions to handle API
changes between kernel version 5.10 and version 5.15.
