dp_display_prepare() only prepares the link in case its not
already ready before dp_display_enable(). Hence separate it into
its own API.
Why?
In the MST use case, this is expected to work as follows: when multiple
sinks (two or more) need to be enabled, dp_display_prepare() handles
link-related setup and should only be executed once, while
dp_display_enable() is responsible for stream-related handling and may
be executed multiple times.
