- 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.
