usb: fixes for v3.8-rc5

Browse source 
Finally we have a build fix for fsl-mxc-udc UDC driver.
 
 We also have a fix for ep0 maxburst setting on DWC3
 which could confuse the HW if we tell it we had way
 too many streams on that endpoint when it _has_ to be
 only one.
 
 cppi_dma support for MUSB got a fix when running as a
 module. By dropping the wrong __init annotation, the
 function will be available even when we're modules and
 we're done with .init.text section.
 
 Last, but not least, we have a fix on FunctionFS which
 was causing a bug on our option parsing algorithm.

  usb: fixes for v3.8-rc5

  Finally we have a build fix for fsl-mxc-udc UDC driver.

  We also have a fix for ep0 maxburst setting on DWC3
  which could confuse the HW if we tell it we had way
  too many streams on that endpoint when it _has_ to be

  cppi_dma support for MUSB got a fix when running as a

  function will be available even when we're modules and
  we're done with .init.text section.

  Last, but not least, we have a fix on FunctionFS which
