Adds the support for the DMA engine withing the timberdale FPGA.
The DMA channels are strict device to host, or host to device
and can not be used for generic memcpy.

This makes the function to get the number of bytes left in the
ongoing DMA transaction actually work: the old code did not take
neither lli:s nor queued jobs into account. Also fix a missing
spinlock while we're at it.

This fixes up the code with a lot of comments that make it readable,
rename things with opaque names like "data" into something more
appropriate, and remove some very confusing BUG() statements.

The xHCI hardware can only handle polling intervals that are a power of

polling interval is rounded down to a power of two, print the original
polling interval in the endpoint descriptor.

USB 3 and Wireless USB specify a logarithmic encoding of the endpoint
interval that matches the USB 2 specification. usb_fill_int_urb() didn't
know that and was filling in the interval as if it was USB 1.1. Fix
usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case
alone, because David Vrabel wants to keep the old encoding.
Update the struct urb kernel doc to note that SuperSpeed URBs must have
urb->interval specified in microframes.
Add a missing break statement in the usb_submit_urb() interrupt URB
checking, since wireless USB and SuperSpeed USB encode urb->interval
differently. This allows xHCI roothubs to actually register with khubd.

This patch removes a double usb_control_msg that sets the cp210x
configuration registers a second time when calling cp210x_set_config.
For data sizes >2 the second write gets corrupted.
The patch has been created against 2.6.34-rc1, but all cp210x driver
revisions are affected.

Contrary to the comment in fsg_add, fsg_bind calls fsg_unbind on errors,
which decreases refcount and frees the fsg_dev structure, causing trouble
when fsg_add does the same.
Fix it by simply leaving up cleanup to fsg_add().
