[PATCH 7/8] ARM: shmobile: Marzen: pass platform data to USB PHY device

[Sergei Shtylyov]

Since we're now going to setup the USBPCTRL0 register using the USB PHY device's
platform data, we now need a way to pass those platform data from the board file
to the device which is situated in setup-r8a7779.c -- and what I'm suggesting is
r8a7779_add_usb_phy_device() that will register USB PHY platform device with the
passed platform data using platform_device_register_resndata() call; creating
this function involves deletion of 'usb_phy_device' from r8a7779_devices_dt[],
so that it will no longer be registered for the generic R8A7779 machine (where
we can't provide the platform data anyway), hence EHCI/OHCI drivers will fail
to load as well.

For the Marzen board, this new function will be called from marzen_init() to
register the USB PHY device early enough.
