usb: fixes for v4.13-rc2 

First set of fixes for the current -rc cycle. Only three fixes on dwc3
 this time around (proper order for getting a PHY reference, fix for
 unmapping DMA and a fix for requesting IRQ on the OMAP glue layer).
 
 Most fixes are on the renesas USB controller, fixing several old bugs
 with most going to stable.
 
 dwc2 also learned that it *must* reset USB Address to zero on Reset
 interrupts.
 
 Apart from these, some drivers needed HAS_DMA dependency and there's a
 sparse warning fix for bdc udc.
