[meta-intel] [PATCH 2/3] dpdk: Move BSP specific configurations from recipes to machine.conf

[Mark Hatle]

The COMPATIBLE_MACHINE entry for dpdk recipes is set to 'null'.  This
will prevent arbitrary machines from trying to use the dpdk functionality.

A compatible MACHINE must define itself as such for the dpdk recipes.  Also
the BSP aware target machine was similarly moved to the BSP.  Embedding BSP
specific knowledge into the recipe will cause the recipe to slowly get out
of date.
