This will give you more bandwidth for isochronous
FULL speed applications connected through a
High Speed HUB.
This patch has been tested with XHCI and EHCI.
MFC after: 1 week
mode in the USB core. The patch mostly consists of updating the USB
HUB code to support USB 3.0 HUBs. This patch also add some more USB
controller methods to support more active-alike USB controllers like
the XHCI which needs to be informed about various device state events.
USB 3.0 HUBs are not tested yet, due to lack of hardware, but are
believed to work.
After this update the initial device descriptor is only read twice
when we know that the bMaxPacketSize is too small for a single packet
transfer of this descriptor.

Refactor how we interface with the root HUB. This is achieved by making a
direct call from usb2_do_request to the host controller for root hub requests,
this call will perform the controller specific register read/writes and return
the error code.
This cuts out a lot of code in the host controller files and saves one thread
per USB bus.

Refactor how we interface with the root HUB. This cuts around 1200 lines of
code totally and saves one thread per USB bus.

- make usb2_power_mask_t 16-bit
- remove "usb2_config_sub" structure from "usb2_config". To compensate for this
"usb2_config" has a new field called "usb_mode" which select for which mode
the current xfer entry is active. Options are: a) Device mode only b) Host
mode only (default-by-zero) c) Both modes. This change was scripted using
the following sed script: "s/\.mh\././g".
- the standard packet size table in "usb_transfer.c" is now a function, hence
the code for the function uses less memory than the table itself.
