libpayload: usb: Reset ohci controller when trying to shutdown ohci
Currently we just disabled ohci interrupts when calling ohci_shutdown,
Which would not actually shutdown the ohci controller, for example it
may still written the increased HccaFrameNumber to Hcca buffer.
Perform a soft reset to ohci controller as the linux kernel ohci-hcd
driver does.
BUG=chrome-os-partner:60996
BRANCH=None
TEST=Checked on gru, no more "BUG: Bad page state" error in kernel.
