When building qTDs (sTDs) from a scatter-gather list, the length of the
qTD must be a multiple of wMaxPacketSize if the transfer continues into
another qTD.
This also fixes a link failure on configurations for 32 bit processors
with 64 bit dma_addr_t (e.g., CONFIG_HIGHMEM_64G).

Add the wusb_phy_rate sysfs file to Wireless USB host controllers. This
sets the maximum PHY rate that will be used for all connected devices.

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).

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.

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.

Provide a endpoint_reset method to reset sequence number and current
window. This QHead information can only be changed while the qset is
not in a schedule.

Add asl, pzl and di debugfs files to uwb/uwbN/wusbhc for WHCI host
controller. These dump the current ASL, PZL and DI buffer.

A driver for Wireless USB host controllers that comply with the
Wireless Host Controller Interface (HCI) specification as published by
Intel.
The latest publically available version of the specification (0.95) is
supported (except for isochronous transfers).
