usb: fixes for v3.5-rc3

Browse Source 
A few remaining fixes for our v3.5 cycle containing a fix
 for a long standing bug which would cause musb to starve its
 dma channels by never releasing them, a build fix on lpc32xx_udc,
 another fix to Ido's endpoint descriptor series on fsl udc, a
 fix to the order of arguments on twl6030-usb driver and a
 fix to dwc3's dequeue method.
 
 All patches have been pending on the list for quite a while.
