CONFIG_OF_DEVICE is going away, so use CONFIG_OF instead. It does not
appear that CONFIG_OF_DEVICE was the correct dependency either.

This driver will be used for every Freescale SoC which has this misc
memory layout to control the basic usb handling. So better name this
driver, function and struct names in a more generic way.

i.MX usb controllers share non-core registers, which may include
SoC specific controls. We turn it into a usbmisc device and usbmisc
driver set operations needed by ci13xxx_imx driver.

For example, Sabrelite board has bad over-current design, we can
usbmisc to disable over-current detection.

msm glue layer compiles on all arches just
fine. Let's drop the unnecessary ARCH check
so we have easier compile tests.

This adds EHCI host support to the chipidea driver. We want it to be
part of the hdrc driver and not a standalone (sub-)driver module, as
the structure of ehci-hcd.c suggests, so for chipidea controller we
hack it to not provide platform-related code, but only the ehci hcd.

The ehci-platform driver won't work for us here too, because the
controller uses the same registers for both device and host mode and
also otg-related bits, so it's not really possible to put ehci registers
into a separate resource.

This is not a pretty solution, but the alternative is exporting symbols
from the chipidea driver to a ehci-chipidea driver and doing all the
module refcounting.

Split the driver into the following parts:
  * core  -- resources, register access, capabilities, etc;
  * udc   -- device controller functionality;
  * debug -- logging events.

Since chipidea is a dual role controller, it makes sense to move it
to its own directory, where we can also have host, otg and platform
code related to this controller. It also makes sense to break out
the driver into several compilation units like udc, host, debugging
code, etc.

Firstly, let's move the udc and platform code to drivers/usb/chipidea.
