Commit b416191a14770c6bcc6fd67be7decf8159b2baee (Fix EHCI port reset.) didn't
move the code that checked for successful clearing of the port reset bit from
ehci_submit_root(), relying on wait_ms() call instead. The mentioned code also
erroneously reported port reset state when the reset was already completed.

In USB ehci driver, the port reset is not terminated. EHCI spec says "A host
controller must terminate the reset and stabilize the state of the port within
2 milliseconds". Without termination, a port stays at reset state. This is
observed on ppc4xx(sequoia) boards.
