[RFC v3 00/11] ci13xxx: langwell/penwell support and some fixes

[Alexander Shishkin <alexander.shishkin@xxxxxxxxxxxxxxx>]

Hi,

This is the 3rd version of the patchset to support langwell/penwell version
of ChipIdea block together with some fixes and reworks that are necessary or
will be useful for future driver improvements.

This patchset also includes conversion to platform_device, which in case if
msm is only compile-tested. While at it, I have also converted "choice" of
UDC controllers into a menu, since we can probably have more than one UDC
in the system, at least theoretically.

It also converts ci13xxx_udc to the "new style", so that we can finally get
rid of the global _udc pointer and theoretically can now have as many chipidea
gadgets in the system as we please.

New since the previous version:
  * one tiny cleanup added
  * "rename register layouts" redone to address Felipe's suggestion and now
    merges access fuctions for different register blocks, although it doesn't
    have impact on the final interface (see mail thread [1] on chipidea
    register access difficulties)
  * register access tables are filled with absolute register addresses at
    probe time to avoid extra branching and whatnot
  * "new style" gadget.
