usb: make usb port a real device
This patch turns each USB port on a hub into a new struct device. This
new device has the USB hub interface device as its parent. The port
devices are stored in a new structure (usb_port), and an array of
usb_ports are dynamically allocated once we know how many ports the USB
hub has.
Move the port_owner variable out of usb_hub and into this new structure.
A new file will be created in the hub interface sysfs directory, so
add documentation.
