eal: add PMD_REGISTER_DRIVER macro

Rather than have each driver have to remember to add a constructor to it to make
sure its gets registered properly, wrap that process up in a macro to make
registration a one line affair.  This also sets the stage for us to make
registration of vdev pmds and physical pmds a uniform process
