The generic plaftorm device for ChipIdea drivers is probed by calling
ci_hdrc_probe. The device structure used is not the one of the specific
ChipIdea driver but the one of the generic ChipIdea platform device.

This results in not being able to probe the PHYs as we're not using the
right device structure. Since all ChipIdea drivers are retrieving their
PHYs in their specific driver code, this didn't impact any of them yet.

Fixes it using the right device structure (dev->parent).

usb: patches for v3.19 merge window

This time, a very pull request with 216 non-merge
commits. Most of the commits contained here are
sparse or coccinelle fixes ranging from missing
'static' to returning 0 in case of errors.

More importantly, we have the removal the now
unnecessary 'driver' argument to ->udc_stop().

DWC2 learned about Dual-Role builds. Users of
this IP can now have a single driver built for
host and device roles.

DWC3 got support for two new HW platforms: Exynos7
and AMD.

The Broadcom USB 3.0 Device Controller IP is now
supported and so is PLX USB338x, which means DWC3
has lost is badge as the only USB 3.0 peripheral
IP supported on Linux.

Thanks for Tony Lindgren's work, we can now have
a distro-like kernel where all MUSB glue layers
can be built into the same kernel (statically
or dynamically linked) and it'll work in PIO (DMA
will come probably on v3.20).

Other than these, the usual set of cleanups and
non-critical fixes.

MUSB currently breaks badly if we try to build in support
for multiple platforms. This also happens if done as loadable
modules, which is not nice for distros.

Let's fix the issue by adding new struct musb_io for the IO
access functions that the platform code can populate. Note
that we don't want to use the current ops as that's really
platform_data and and set as a const.

This should allow eventually adding function pointers also
for the DMA code to struct musb_io, but that's a whole
different set of patches. For now, let's just fix the PIO
access.
