USB: EHCI: initialize data before resetting hardware
Currently, EHCI initialization turns off the controller (in case it was left running by the firmware) before setting up the ehci_hcd data structure. This patch (as1565) reverses that order. Although it doesn't matter now, it will matter later on when future additions to ehci_halt() will want to acquire a spinlock that gets initialized by ehci_init().
