USB: ehci-orion: Call ehci_reset before ehci_halt
I noticed that USB initialization didn't setup correctly on my kirkwood
based board (OpenRD base) if I hadn't initialized USB in U-boot first.
The error message looks like this:
ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
orion-ehci orion-ehci.0: Marvell Orion EHCI
orion-ehci orion-ehci.0: new USB bus registered, assigned bus number 1
orion-ehci orion-ehci.0: can't setup
orion-ehci orion-ehci.0: USB bus 1 deregistered
orion-ehci orion-ehci.0: init orion-ehci.0 fail, -110
orion-ehci: probe of orion-ehci.0 failed with error -110
which is caused by ehci_halt() timing out in the handshake() call. I
noticed that U-boot does a reset before calling handshake(), so this
patch does the same thing for Linux. USB now works for me.
