USB: straighten out port feature vs. port status usage
This patch (as1349b) clears up the confusion in many USB host
controller drivers between port features and port statuses. In mosty
cases it's true that the status bit is in the position given by the
corresponding feature value, but that's not always true and it's not
guaranteed in the USB spec.
There's no functional change, just replacing expressions of the form
(1 << USB_PORT_FEAT_x) with USB_PORT_STAT_x, which has the same value.
