Sorry, but you can not do that. Premium wont transfer to your other platforms, as cross platform premium transfer is not possible. Also Origin itself, is only for PC platform, PS and Xbox have there own accounts. You can link this, but premium still wont transfer and you will still have 3 accounts (if you have PC, PS and Xbox).
If you still what to link them, follow this steps: http://help.ea.com/en/article/linking-your-gamertag-psn-id-or-ea-classic-screen-name/ .
Again, this will not transfer your premium to other platforms.
