f0ad073f04 USB: whci-hcd: fix type and format warnings in sg code
Fix type and format warning in the new sg code.  Remove the very chatty
debug messages that were left in by mistake and use min_t() as required
(no one seems to agree on a type for buffer sizes).

294a39e782 USB: whci-hcd: support urbs with scatter-gather lists
Support urbs with scatter-gather lists by trying to fit sg list elements
into page lists in one or more qTDs.  qTDs must end on a wMaxPacketSize
boundary so if this isn't possible the urb's sg list must be copied into
bounce buffers.

831baa4915 USB: whci-hcd: make endpoint_reset method async
usb_hcd_endpoint_reset() may be called in atomic context and must not
sleep.  So make whci-hcd's endpoint_reset() asynchronous.  URBs
submitted while the reset is in progress will be queued (on the std
list) and transfers will resume once the reset is complete.

not in a schedule.
