Subject: [patch] usbnet cdc_subset: fix issues talking to PXA gadgets

From: David Brownell <dbrownell@...rs.sourceforge.net>

The host-side CDC subset driver is binding more specifically
than it should ... only to PXA 210/25x/26x Linux-USB gadgets.

Loosen that restriction to match the gadget driver itself.
This helps various PXA 27x and PXA 3xx devices be happier
when talking to Linux hosts; and a few other gadgets too.

Appropriate for -stable ... behaves like a protocol bug.
