Hi all,

this is a re-submission of Bin Liu's patch that was 
reverted by the commit 16b61d13bab361853564da401b15fc34ae1dfea7
from Daniel Mack.

It is not OK to set the MUSB_POWER_HSENAB unconditionally because
there are sometimes some HW limitations that allow only FULL SPEED.

In our case  we have some bad wiring protection in our USB circuit
that acts as a filter an will not allow signals to pass that
are faster than FULL SPEED.

I suggest to use CONFIG_USB_GADGET_DUALSPEED define to enable 
HIGH SPEED as it was done previously, which is by default 
enabled. 

Kind regards

Sam
