Add a USB2 ChipIdea driver for ci13xxx, with optional PHY, clock
and DMA mask, to support USB2 ChipIdea controllers that don't need
specific functions.

Tested on the Marvell Berlin SoCs USB controllers.

The USB controller in TI-NSPIRE calculators (LSI Zevio SoC) are based off either
Freescale's USB OTG controller or the USB controller found in the IMX233, both
of which are Chipidea compatible.

This patch adds a device tree binding for the controller.

The ci_hdrc_imx's probe needs usbmisc_imx to be loadded beforehand,
so it is better we load usbmisc_imx first.

This file is mainly used to access otgsc currently, it may
add otg related things in the future.

Pull device tree updates from Grant Likely:
 "This branch contains the following changes:
   - Removal of CONFIG_OF_DEVICE, it is always enabled by CONFIG_OF
   - Remove #ifdef from linux/of_platform.h to increase compiler syntax
     coverage
   - Bug fix for address decoding on Bimini and js2x powerpc platforms.
   - miscellaneous binding changes

  One note on the above.  The binding changes going in from all kinds of
  different trees has gotten rather out of hand.  I picked up some
  during this cycle, but even going though my tree isn't a great fit.

  Ian Campbell has prototyped splitting the bindings and .dtb files into
  a separate repository.  The plan is to migrate to using that sometime
  in the next few kernel releases which should get rid of a lot of the
  churn on binding docs and .dts files"

"ci13xxx" is bad for at least the following reasons:
  * people often mistype it
  * it doesn't add any informational value to the names it's used in
  * it needlessly attracts mail filters

This patch replaces it with "ci_hdrc", "ci_udc" or "ci_hw", depending
on the situation. Modules with ci13xxx prefix are also renamed accordingly
and aliases are added for compatibility. Otherwise, no functional changes.

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.
