Subject: [PATCH v3 15/37] drm/atomic-helper: Change parameter name of
 crtc_set_mode()

crtc_set_mode() deals with calling the modeset related hooks for CRTC,
connectors and bridges if and when a new commit changes them. It takes
the drm_atomic_state being committed as a parameter.

However, that parameter name is called as old_state, which is pretty
confusing. Let's rename that variable as state.
