Division with round up is the correct way to compute this even if the
only case where division with round down gives incorrect result is
probably 15 bpp. This case was explicitely patched up in one of these
functions but was unhandled in the other. (I'm not sure about setting
16 bpp for the 15bpp case either but I left that there for now.)

brcond and setcond ops are not commutative, but it's easy to compute the

This patch changes the way xhci ports are linked to USBPorts. The fixed
1:1 relationship between xhci ports and USBPorts is gone. Now each
USBPort represents a physical plug which has usually two xhci ports
assigned: one usb2 and ond usb3 port. usb devices show up at one or the
other, depending on whenever they support superspeed or not.
This patch also makes the number of usb2 and usb3 ports runtime
configurable by adding 'p2' and 'p3' properties. It is allowed to
have different numbers of usb2 and usb3 ports. Specifying p2=4,p3=2
will give you an xhci adapter which supports all speeds on physical
ports 1+2 and usb2 only on ports 3+4.
Change the register layout to be a bit more sparse and also not depend
on the number of ports. Useful when for making the number of ports
runtime-configurable.
This patch splits the xhci_xfer_data function into three.
The xhci_xfer_data function used to do does two things:
(1) copy transfer data between guest memory and a temporary buffer.
(2) report transfer results to the guest using events.
Now we three functions to handle this:
(1) xhci_xfer_map creates a scatter list for the transfer and
uses that (instead of the temporary buffer) to build a
USBPacket.
(2) xhci_xfer_unmap undoes the mapping.
(3) xhci_xfer_report sends out events.
The patch also fixes reporting of transaction errors which must be
reported unconditinally, not only in case the guest asks for it
using the ISP flag.
