[powerpc*] udeb: Remove redundant lines from nic-modules

The bmac, ehea, ibmveth, ps3_gelic, spidernet, sungem, sungem_phy,
and sunhme drivers are built under drivers/net/ethernet so don't
need to be specifically included.  pasemi_mac has been renamed to
pasemi_mac_driver, and is also under drivers/net/ethernet.

The ehea, ps3_gelic, and spidernet drivers then don't need to be
excluded on ppc64el.

Make the airport driver optional now, so that it doesn't need to be
excluded on ppc64el.  I will move it to nic-wireless-modules next.
