If userspace set blnd colorop to bypass, AMD driver just skips blnd
transfer function configuration. Currently, this is not an issue since
dc plane state is a reset/default state, but it's not fully correct and
doesn't mirror shaper tf helper. Make bypass mode setup clear by
initially set tf->type as BYPASS and let the helper change its type
according to userspace requests.
