First set of fixes for the gadget side. Not much this time around,
things have been rather calm.

In no order whatsoever, this pull request contains:

- A DMA starvation fix on dwc3 caused by some recent changes to how we
  map/unmap requests

- A build error fix on the snps_udc_plat.c driver

- A fix for how to we call ->udc_set_speed()

- Spinlock recursion fix on the printer gadget

- Removal of pointless comparisons on dummy driver
