USB: EHCI: fix remote-wakeup support for ARC/TDI core
This patch (as1147) fixes the remote-wakeup support for EHCI controllers using the ARC/TDI "embedded-TT" core. These controllers turn off the RESUME bit by themselves when a port resume is complete; hence we need to keep separate track of which ports are suspended or in the process of resuming. The patch also makes a couple of small improvements in ehci_irq(), replacing reads of the command register with the value already stored in a local variable.
