drm/bridge: cdns-dsi: Switch to atomic_create_state

Browse Source 
The cdns-dsi bridge atomic_reset implementation is semantically an
atomic_create_state: it allocates and initializes a pristine state
without side effects.

Switch to the atomic_create_state callback, and rename the function
accordingly.
