Revert "usb: ehci-platform: support no relinquishing port quirk"

This reverts commit 0fd1853df055.

We found this commit just work well for HS devices, however,
ehci_hub_control will set port owner to companion according line
status bits when FS/LS device is plugged in, so revert this one
and introduce a new workaround.
