[RPI-B] [HEADS UP] DWC OTG TX path optimisation for 11-current

[Hans Petter Selasky]

Hi,

I finally had the time to sit down and test Daisuke Aoyama's DWC OTG 
patches. I've modified his patch a bit and ensured it works with all 
transfer types, everything from USB keyboards, memory sticks, USB audio 
devices to USB network devices. I found some bugs with the initial patch 
from Daisuke, fixed these and made the following commit:

If you have more patches and improvements please make a new patch!

And if you see some network numbers go up, you can post them here :-)

Or if you find regressions.
