The UDC in Intel's "Bulverde" processors is incompatible with the
one in their PXA 25x/26x/21x processors, and has different sorts
of restrictions.  For example, it can implement real CDC Ethernet,
while the earlier (PXA 25x etc) can't.


This adds a gadget_is_pxa27x() function and uses it appropriately in the
current set of gadget drivers.  (And moves an LH7A40X entry to the right
place in "ether.c").
