[PATCHv4 2.6.34-rc4 6/7] mxc-usb: Add call to initialize MXC USB HW registers

From: Dinh Nguyen <Dinh.Nguyen at freescale.com>

The placing of the function needs to be before setting the USBMODE
register to host, since a reset and start is done in
mxc_initialize_usb_hw.

This patch applies to 2.6.34-rc4.
