There are still some instances in the USB hub driver where port power is
directly controlled by toggling the USB_PORT_FEAT_POWER feature flag.

Switch these instances over to usb_hub_set_port_power() so that only one
unified function to do this exists. This makes adding external power
control with the power sequencing API easier and consistently applied.
