[Beignet] [PATCH] Add the pci id support for gbe_generate

[Yang, Rong R]

This patch detect the building platform's pci id and generate the bin for host when building, it is necessary to generate the corresponding binary for IVB and HSW.
I think support cross platform bin generate and use a string in command line is next step.

You directly use pcid, right?
What about changing to use a string as the command argument. Like 'ivb', 'hsw'?
That would be meaningful for users.

Thanks!
