[PATCH 02/10 v3] usb: usb251xb: Add USB2517i specific struct and IDs

[Serge Semin <fancer.lancer@gmail.com>]

There are USB2517 and USB2517i hubs, which have almost the same
registers space as already supported USB251xBi series. The difference
it in DIDs and in a few functions. This patch adds the USB2517/i data
structures to the driver, so it would have different setting depending
on the device discovered on i2c-bus.
