[PATCH 126/133] [Jaunty SRU] ARM.imx51 Freescale:ENGR00113331 set host mode after usbcmd reset for ehci_run.

[Brad Figg]

From: Jun Li <r65092 at freescale.com>

For those designs that contain both host & device capability,
the controller will default to an idle state and will need to
be initialized to the desired operating mode after reset.
For combination host/device controllers of FSL, SW need program
USBMODE register to make controller to be in host mode.
