  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
  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.
