Building a kernel for imx_v4_v5_defconfig with CONFIG_USB_ULPI disabled, results
in the following error:
arch/arm/mach-imx/built-in.o: In function 'pca100_init':
platform-mx2-emma.c:(.init.text+0x6788): undefined reference to 'otg_ulpi_create'
platform-mx2-emma.c:(.init.text+0x682c): undefined reference to 'mxc_ulpi_access_ops'
Fix this by providing a no-op definition of *otg_ulpi_create for the case when
CONFIG_USB_ULPI is not defined.

Use struct usb_otg members with OTG specific functions instead
of usb_phy members.

This is the first step in separating USB transceivers from
USB OTG utilities.
Includes fixes to IMX code from Sascha Hauer.

Add generic access ops for controllers with a ulpi viewport register
(e.g. Chipidea/ARC based controllers).

1) Introduce ulpi specific flags for control of the ulpi phy
2) Extend the generic ulpi driver with support for Function and
Interface control of upli phy
3) Update the platforms using the generic ulpi driver with new ulpi
flags
4) Remove the otg control flags not in use

This adds a minimal generic driver for ULPI connected transceivers,
using the OTG framework functions recently introduced.
The driver got a table to match the ULPI chips, which currently only has
one entry for NXP's ISP 1504 transceiver.
