Most of NXP (Freescale) i.mx USB part has HSIC support, in this series,
we add support for them, it should cover all imx6 and imx7d SoC.

Changes for v2:

As I already posted when I was testing v1 last week, there is a problem 
with auto suspend with my LAN9730 chip. I thought it was a problem with 
the smsc95xx/usbnet driver, but I'm not so sure anymore.

So I'd like to figure out if it has something to do with the HSIC 
patches. I hope to find some time to do some more debugging soon.
When this is sorted I will append my R-b, T-b tags.

Regards,
Frieder
