i2c-tiny-usb: New VID/PID pair

I have recently bought some USB PIDs from EZPrototypes for my USB projects
and one will be for the i2c-tiny-usb. I have not yet started to use the new
one in the official i2c-tiny-usb firmware since i think it makes sense to get
the change into the kernel before releasing a modified firmware.

This patch adds support for the EZPrototypes USB vid/pid pair used in later
i2c-tiny-usb firmware versions (avrusb v1.06 and up, usbtiny v2.06 and up).
