[PATCH] UHCI: remove hc_inaccessible flag
This patch (as706) removes the private hc_inaccessible flag from
uhci-hcd. It's not needed because it conveys exactly the same
information as the generic HCD_FLAG_HW_ACCESSIBLE bit.
In its place goes a new flag recording whether the controller is dead.
The new code allows a complete device reset to resurrect a dead
controller (although usbcore doesn't yet implement such a facility).
