Tweak USB stack to allow endpoints with no queue.
Add back legacy USB bulk I/O code, because it worked so well before... despite being kinda simplistic.
Tweak linker scripts:
Add explicit flash region.
Resize aliased RAM region to match actual RAM on LPC4330.
Move M0 to a different block of memory.
Remove references to AHB regions reserved for SGPIO/USB DMA.
Add sleep RAM region.
