This handles the case where the host sends a new setup packet
in the middle of an ongoing control transfer.

IMHO the current name is somewhat misleading:
- usb_drv_send() is blocking and we have usb_drv_send_nonblocking()
for the non-blocking case. This inconsistent naming can only
promote confusion. (And what would we call a blocking receive?)
- Other hardware abstraction APIs in Rockbox are usually blocking:
storage, LCD, backlight, audio... in other words, blocking is the
default expected behavior, with non-blocking calls being a rarity.

This only required a minor patch to the usb-designware driver due
to DMA requiring physical addresses -- on the X1000, these differ
from virtual addresses so we have to do the usual conversion.
Both the mass storage and HID drivers work, but there are a few
issues so this can't be considered 100% stable yet.
- Mass storage might not be detected properly on insertion,
and USB has to be replugged before it shows up
- HID driver may occasionally panic or hang the machine
