drm/bridge: cdns-dsi: Fix the _atomic_check()

Browse Source 
Use the "adjusted_mode" for the dsi configuration check, as that is the
more appropriate display_mode for validation, and later bridge enable.

Also, fix the mode_valid_check parameter from false to true, as the dsi
configuration check is taking place during the check-phase, and the
crtc_* mode values are not expected to be populated yet.
