[PATCH 4.1 060/102] usb: host: ehci-sys: delete useless bus_to_hcd conversion

From: Peter Chen <peter.chen@freescale.com>

commit 0521cfd06e1ebcd575e7ae36aab068b38df23850 upstream.

The ehci platform device's drvdata is the pointer of struct usb_hcd
already, so we doesn't need to call bus_to_hcd conversion again.
