Felipe writes:

usb: fixes for v4.5-rc6

The most important fixes here are:

a) yet another fix to dwc3's EP transfer resource
assignment logic. This time around we will be
pre-allocating transfer resources to avoid any
future issues;

b) two DMA fixes for the old MUSB driver.

c) dwc2's data toggle fix for FS

Other than these, we have a few other minor fixes
elsewhere.
