[PATCH] USB: plusb: Add support for PL-2501

This patch adds support for PL-2501 by adding the appropriate USB
ID's. This chip is used in several USB 'Easy Trasfer' Cables.

Signed-off-by: Mikhail Peselnik <peselnik@xxxxxxxxx>
Tested-by: Mikhail Peselnik <peselnik@xxxxxxxxx>
Now with proper sign-offs and right people in cc and unwrapped lines.
plusb driver (drivers/net/usb/plusb.c) doesn't recognize PL2501 chip.
Since PL2501 uses the same code as PL2301/PL2302 (PL2501 works in
compatibility mode with PL2301/PL2302), the fix is trivial and
attached as a patch.

Just to note: the patch is not mine, it can be found here and there on
I've tested the patch and it works great.

Thank you.
