drm/bridge: cdns-mhdp8546: Return an error pointer on allocation failure
The drm_bridge_funcs.atomic_reset documentation states that the hook
must return either a valid drm_bridge_state object or an ERR_PTR().
The cdns_mhdp_bridge_atomic_reset() callback returns NULL when the
allocation of its state fails, violating this contract.
Return ERR_PTR(-ENOMEM) instead.
