drm/probe-helper: Add drm_crtc_helper_mode_valid_fixed()
Add drm_crtc_helper_mode_valid_fixed(), which validates a given mode
against a display hardware's mode. Convert simpledrm and use it in a
few other drivers with static modes.
v4:
* remove empty line after opening brace
v2:
* rename 'static' and 'hw' to 'fixed' everywhere
